the effect of temperature on a tennis ball experiment

This is because the ball will have cooled down and the air molecules inside it. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. The stiffness tests closely approximated the expected result that stiffness would have an inverse relationship to increase in temperature. Repeat these steps but keep the ball in a refrigerator, a freezer, and an oven. According to Aleks Szymanski from tennisletics.com, tennis balls are hollow and contain air that expands in the event of high temperatures, causing the balls to bounce more freely. (Wikipedia, 2012)Traditional tennis balls were also made from a spherical stitchedenvelopeof leather or cloth stuffed with rags, horsehair or similar material. Results for Setup #1 tension loss vs timing of heat application. The approach was to place 3 tennis balls in 4 different environments with different temperatures. They found that tennis rackets perform noticeably differently at different temperatures, as well as be affected by the conditions during which stringing itself takes place. The scientific equation for determining the pressure of gas is p=rRT, where p is the pressure, r is the density, R is a constant specific to the gas and T is temperature. By far the cubic fit is the best out of the three regression models analyzed but the R squared values are all well below 0.9 which is what would be needed as a minimum to make the models good predictors for future trials. The balls which were placed in a refrigerator had a bounce percentage of 62.25. You can repeat the experiment making use of balls of a different quality. On the other hand, the thermal energy of a warmer string helps break weak bonds between molecule chains, allowing greater flow and elongation of the string during stretching. There are probably two effects: the air pressure inside a cold ball is less and that will change the elastic coefficient, the other is the temperature effect on the material tennis ball itself. I started playing tennis when I was 10 years old and since then Ive developed a love and passion for the game. Is a Photograph equally sharp in all area? Dependant variables:How High the Ball Bounces. Do variations in temperature exposure affect tension loss in these materials differently? Ball 1 had a sample standard deviation of 3.312 while ball 2 was 3.177. Record the temperature on the thermometer. The air molecules inside the ball will also move around slowly and tend to have less energy when the ball has been cooled down, meaning that the ball will have a lower bounce when you drop it to the ground. Add up all the ten readings and divide them by ten to find the mean height to which each ball could bounce back to at a specific temperature. Hi my name is Charly i was doing this project and i did`n know how to do this. Later, the data would be compared by calculating the percentage of the bounce height over the initial height. Standing on the strong chair will have a better height to drop the balls from, which means that the results will be more accurate. Repeat steps 1-3 but keep the ball in a refrigerator. cuz in my experiment i got some mixed up results. The strings were each given an Identification number from 1-15 (14 was omitted). Click the "Experiment" button to find out! After the 20 minutes, take out the ball. Elongation also behaved as expected it increased with temperature (Figure 9). Upon conclusion, I am to determine why resistance was limited during the activity. A residual analysis was next completed for the liner regression. Copyright 2023 Elite Tennis Guide | All Rights Reserved. It is true that temperature greatly affects the pressure of a tennis ball; temperature can increase and reduce pressure of a tennis ball, depending on the heat added or taken away; this would benefit people designing objects to absorb shock. Temperature Cubic ANOVA, Table 14: Ball 2 vs. (Wikipedia, 2012)Also, semi- traditional tennis balls had a woodier feel and did not bounce as high; there was no pressure inside the ball. A thousand seconds after achieving target tension and being clamped off, the string that took only 1 second to stretch to target tension lost almost 3 Kg more tension than the one that took 26 seconds. Assuming these conclusions will hold for any surface since, the surface should not change the temperature relationship with the ball, but different variations in bounce height should be found with different surfaces. As bonds break and reorient, tension decreases. Stiffness and elongation are proportional to temperature, though the effect is not great. The impact duration was between 65 and 71 ms. As such, gas molecules can easily expand or contract. The second apparatus was a materials testing machine (Figure 4). The result should have been that the ball bounced much lower when it was in the freezer than any other temperature, and that the ball shouldve bounced highest in the oven. . A typical result is shown in Figure 5 at 20 C. Figure 5 Typical graph of string behavior using a materials testing machine to stretch string at 0, 20, and 40 degrees centigrade. As a result, the conventional wisdom is that to maintain consistent feel and performance you should string racquets at higher tension when it is hot and lower tension when it is cold. Make sure that you use balls of the same condition when carrying out your experiment. One may also use a heat dish to do this. Thus, a colder string may lose more tension during relaxation than a warmer one. Bocce has really become such a widespread sport because you can participate no matter how old, what your race is, or what gender you are. After the tennis ball reforms into its original shape, the gas inside the ball pushes back up and causes the ball to bounce into the air. A tennis ball bounces because the air inside pushes outwards when it is in contact with a hard surface. Signature: ___________________________________________________. Crawford Lindsey, Tennis Warehouse, San Luis Obispo, CA. Analyze the data, and make a conclusion stating if the temperature of a tennis ball affects how high it bounces. Temperature is either something that is cold or hot. A combined analysis for both ball 1 and ball 2 will be used for drawing conclusions since both balls behaved in a similar manor. As the molecules expand, their energy increases as they bounce around more erratically. In the study, they considered strings of different materials under different temperatures. At 200 seconds, the string was heated to 40 C. This took about 100 seconds. What is the effect of. In doing this, high percentages of the efforts are normally exerted at the upper extremity of the body, while the rest at the lower extremity of the body. If you are looking to add a bit of friendly sabotage to your tennis opponents game, consider popping a few of his tennis balls in the freezer beforehand. After doing this activity, I observed that as temperature decreases so does the pressure. Make sure there are no liquids in the freezer. Researchers Crawford Lindsley and Rod Cross performed an in-depth study exploring the effect of temperature on string tension and stiffness. Its also worth noting some of the less short-term effects on racket stringing. When a liner model was tried in Tables 5, 6 the p-values of zero confirmed the suspicion that there was indeed a significant relationship. A further study should be completed to see if anything else effects the balls differently to try and determine what makes the balls different. The colder air will also have molecules closer together, and they will also tend to be more inert in the sense that they will not be able to move around much. Copyright 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. As you will notice from your experiment, the balls that have been treated to the ice chest with ice in it will tend to have lower bounces, resulting from the molecules moving around less and containing less energy. The main. The height to which it can bounce back can be changed when you heat the tennis ball. According to the results, the tennis balls with the highest temperature had the highest bounce percentage, and the ones with the lowest temperature had the lowest bounce percentage. Stress relaxation occurs both during and after stretching. The player may also feel stiffer on a cold day. Once the arm has begun to accelerate towards the ball, the tricep brachii is then used to, The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. The string ends extended past the end of the tube and were clamped. What players feel when hitting in various temperature conditions is the combined effect. The amount is highly material specific, with gut, nylon, and polyester losing the least tension in that order. First, watch the video. The higher the percentage, the higher the ball bounced. String materials vary in terms of their durability, given extreme weather conditions. Some interesting results can be found in an analysis of the experiment results. Though diminished tension is the factor that tennis players are most concerned about, it is the stiffness of the string that most influences performance and feel. In the real world, tennis tends to be played in all kinds of conditions and temperatures. The expected result was that the tension loss would increase for each string by about the same amount, regardless of whether it was heated before tensioning or after tensioning. And we saw in Figures 7 and 8 that stiffness is proportional to temperature. Tension loss is due to the reordering of molecular bonds to the lowest stress equilibrium available at any given moment. As a result, a cold ball has a much lower bounce. Web. The regression Graphs 3, 4 show R squared values considerably higher than any of the time regression models. The other end was attached to a hand crank that pulled the clamp in the rig to stretch the string. The machine stretched the string at 100 mm/min until tension reached 280 N. There was a 100 second wait during which tension loss was recorded. When you have heated the balls, you will have provided them more energy to move about, and as such, they will be able to bounce to higher heights when they are dropped to the ground. Ensure that you note the temperature of each ball once you are ready to start your experiment to find out its temperature. Retrieved 8 24, 2012, from Wikipedia: http://en.wikipedia.org/wiki/Tennis_ball, Your email address will not be published. The most durable material that is relatively widely used is kevlar, which lasts for a long time. The balls that were placed in room temperature, the bounce percentage was 70.10. You should find that the heated balls bounce the highest, followed by the room temperature balls, then the refrigerated balls, with the frozen tennis balls bouncing the least. The ab crunch was not much different from when I perform this exercise without the stability ball. Place the tape measurer against the edge of a wall using the bluetack 3. On the other hand, a temperature decrease causes the gas molecules to contract and move around more sluggishly. The tennis serve begins with flexion of the knee joint caused by the hamstrings. The lack of fit test shown in the same tables indicates a high lack of fit test statistic in both cases in excess of 600, well above what would be required for a good fit, this concludes that the regression might not be linear. Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. Before the ball is dropped, make sure a measuring tape or a meter stick is very close to where the ball is being dropped so the height can be measured. Natural gut string is generally more responsive to changes in temperature. british airways seat size; moen bathroom faucets single handle; eardwulf the last kingdom sister The bladders are usually made of rubber or rubber like things. Strong chair Pickleball Spin Why Is A Rubber Hitting Surface Illegal? (Harriman, 2012)When the temperature increases, the gas molecules expand and as they expand, the energy of them increases, causing them to bounce more tempestuously. The question of concern was whether adding heat after stabilization would start (or accelerate) tension loss. When looking at bounce ball height, keep your head in the same place to avoid problems with parallax. (Incorporation, 2011)In1972,tennis balls became yellow. The Effect of Temperature, Time, and Humidity on the Bounce of Tennis Balls. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. Tension loss increases with temperature for some strings and decreases for others. This phase was similar to the pre-tensioning heating test but an additional 100 seconds was added to allow tension to stabilize. A good source of heat that can heat things evenly. Your email address will not be published. 1a Heat before tensioning. However, at 63, The learning quesiton that I chose required me to perform atleast one exercise for each major muscle group on a stability ball. This scientific mystery can be demonstrated at home or school with a simple experiment. Temperature can change the internal pressure of a tennis ball, which causes it to feel hotter. Many aspects of the game of Bocce ball can be relatable to the simple concepts of Newtons original three laws, from the balls hitting each other (Newtons third law), to throwing balls harder to increase the force and then slowing down (Newtons first and second laws). Retrieved 8 24, 2012, from ITF Tennis: http://www.itftennis.com/technical/equipment/balls/history.asp, Sheehan, K. (2011, March 11). Tests with this apparatus were conducted at 20 C and 40 C. 20 C was room temperature with air conditioning. The stiffness, k, is calculated as k = dF/dx, where dF is the increase in the force when elongation increases by dx. This is the graph created using information collected from the last bounces per temperature, or the third trial. For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder. When a tennis balls temperature changes, the gas core goes through a reaction. Easy Experiment. On the other hand, a temperature decrease causes the gas molecules to contract and move around more sluggishly. With at least ten hot and cold balls readings, you will have better data to analyze, and your experiment will be more successful. Notebook An experiment was performed to determine the effect of temperature on the stiffness, elongation, tension loss and maintenance of tennis strings. Higher temperature allows weak secondary bonds between the polymer chains to break. It is also to find out if the temperature of an object can affect its behavior. It is common knowledge that most strings lose a large percentage of tension with time and play. (Incorporation, 2011)After, chemicals would generate pressurizing gas which was to be added to the rubber outline. The question also required me to determ wheter or not I could use the same weight as I normally do while using the stability ball? The relatively uncontrollable nature of weather presents a variety of challenges to address to perform at the highest levels. (Incorporation, 2011)It was also composed of a mixture that seemed like putty and human hair. Heating before tensioning would simulate the effect of temperature during the stringing/tensioning process. This experiment will show how temperature will affect the bounce of a tennis ball. Equilibrium occurs when all molecular bond attractions are greater than the tension trying to tear them apart. Then, drop the ball from a height of one meter. Video footage will also be utilised to measure the bounce correctly by watching the film in slow motion. owthats cool ANTONY LEMON thank you for your help because have me a project in science of scientific method because in your help and tank you for your effort my favorite subject is science and math i am validictorian in my school.THANK YOU FOR YOUR EFFORT. Within the industry, resources and tools that leverage artificial intelligence (AI) are becoming available to help players make informed decisions around racket modifications. Background Research For stiffness, nylon seems to be more thermally reactive than polyester, but this is reversed for elongation. Setup #1 Tension vs timing of heat application. in my school i finish up in 2nd place thank u very much. Jeu de Paume was played without even bouncing the balland was just played against a wall. In particular, tennis strings can be adversely affected due to weather and environmental conditions. How does temperature affect the bounce of a tennis ball? As the tennis ball returns to its normal shape, the gas inside the ball acts as a spring and causes the ball to bounce into the air. The thermocouple recorded the temperature. Experiment. Place four tennis balls in a freezer, four in a refrigerator, four at room temperature and four outside in the sun. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); can u pls also mention the results u get by doing the experiment? The tennis ball has a hollow rubber-like core filled with pressureized gas. History Of Tennis Balls Who Invented The Tennis Ball? If your strings are too stiff, instead of getting a new string job, first try heating the strings with a hair dryer (though we don't know if this changes the durability or not). Bocce ball, which was first documented in the year 5200 B.C., is a sport that was first popularized during the roman empire. Synthetic materials hold up better, on the other hand. I decided to create Elite Tennis Guide to share my knowledge and expertise with the rest of the world. That is, it is more susceptible to wear in unfavorable conditions. But if heat exposure occurs after tensioning and stabilization, the molecules become agitated and begin to move relative to each other. Figure 7 is qualitative in that the horizontal axis is simply the itemization of each string, and thus each curve does not demonstrate any quantitatively causative relationships. With this, it will look at the movements that occur at each of the upper extremity together with the muscles that are in use at the joints. Once you have the right conditions under which to carry out your experiment, you can go ahead and start gathering the materials that will be needed. If we graph post-relaxation stiffness vs temperature for each string, we begin to see some patterns. Likewise, will a tennis racquet perform differently at different temperatures, or will the stringbed stiffness be affected if the racquet is strung at different temperatures? Now the equilibrium between the tension and the bonds is broken. (Incorporation, 2011)The spherical rubber would then be molded to an actual sphere in heated cavities. Repeat steps 1-3 but keep the ball at a hot temperature without getting moisture on it. The first setup (Figure 1) was used to measure tension vs time for strings with different temperature exposure histories. The p-value remains, as it should at zero, when the regression was plotted in Graph 5, 6 the R squared value showed little improvement, few points are still predicted by the regressed line. When a tennis ball is compressed, its internal air pressure is boosted. Two variables will be omitted in the study, how much the ball is played with and different court surfaces. As shown in Figure 10, elongation is proportional to temperature. Take 2 tennis balls and put them in the slow cooker for 10 mins. Figure 12 zooms in on tension loss behavior for each nylon and polyester string. (Harriman, 2012)Likewise, a colder temperature causes the gas molecules to contract and move around more sluggishly. Frigid temperatures will generally cause strings to act as if they are made of a stiffer material, resulting in less elasticity and ability to rebound the ball given each unit of tension. You can also experiment within an enclosed space to ensure that the blowing wind does not affect the bounce of your ball. Purpose The purpose of this project is to determine how tennis balls are affected by different temperature conditions. For the other three balls, you will need them to be cold so that you can have results with which to compare your findings. Secondly, testing our experiment with two different balls of the same type to ensure that they reflect the same amount of result. This is the table showing the heights in which the ball bounced. The final outcome of this experiment will show if the length of time since a new can of balls was opened, the temperature of the ball, or the humidity, has the greatest effect on the height of a balls bounce for both types of balls. This is an eventuality that many players should take into account. While high temperature and high humidity are technically different measures, they often occur together. Temperature Cubic ANOVA. Place one of the tennis balls in the freezer for 20 mins 2. different types of ball material: rubber (lawn-tennis ball, super ball, soccer ball and squash ball) and plastic (table-tennis ball) at room temperature. Photos of the investigation being conducted Figure 2 For most of the strings tested, there was little difference in tension relaxation between being tensioned at normal room temperature (left or top) and at 40 C (right or bottom). 1b Heat after tensioning and stabilization. Stiffness is the property that measures the result of all these elongation, duration, and relaxation processes. How do variances in tension loss due to temperature changes affect the most important property of string stiffness? Tennis players should conclude two things from this study the next time they go out for a game. This increased energy and movement results in a higher bounce. What mainly causes a tennis ball to bounce is all the pressure stored inside. The courts are designed so that the ball can bounce off any surface and still be in play, yet it is in a confined area so you don't have to run to cover too much territory. It is also an ideal learning opportunity that can show us how the effects of temperature cause variations in the bouncing ability of a tennis ball. (Wikipedia, 2012)From the 18th century, tennis balls were formed by wounding strips of wool around a nucleus made by rolling strips into a tiny ball. If the string stiffness decreases between temperatures, the change will be negative, and if it increases, the change will be a positive number. (2012, 8 22). Tension stabilization continues forever, but at a continually decreasing pace. And according to the experimenters, tension is, in reality, a determinant of stiffness. But there is a possible explanation for the behavior, though it was not measured during the test. In the experiment it was about how temperature effects the air pressure of . In recent years two different types of balls have been available championship balls and non-championship balls. (Borlings, 2011)However, in 1470, Louis XI of Franceforbade the filling of tennis balls and said that they should be filled with high-quality leather. Place the ball at the 100-inch mark and drop it. We are guessing that heat makes the molecules move faster in the bouncy ball, which gives it more elasticity, but I did not find anything in my research of this project that confirms that fact. (Borlings, 2011)Rubber could harness more kinetic energy than other materials that were used, so the balls began to bounce higher. Six tennis balls Hot temperatures create more pressure whereas cold temperatures do not produce much pressure. University of Virginia Physics Department, n.d. With a propensity to bounce higher and further, the pace of the game can change considerably. This scientific mystery can be demonstrated at home or school with a simple experiment. As the molecules expand, their energy increases as they bounce around more erratically. Because of the intense heat or cold, and depending on the material, tennis strings can be significantly affected in ways that change the way the ball reacts to the racket and the players actions. This will give you a visual presentation of the bounce heights and the temperatures, which means that determining whether hot or cold balls can bounce to a higher height will be a lot easier. For this reason, the players will have a better experience which is usually caused by the plenty of pressure inside the tennis ball. Temperature can be measured by. From the things they can controllike diet, rest, and conditioning, to the things that are relatively less predictablelike weather conditions and temperature, good players are continually considering all eventualities. Figure 12 Tension vs time for a string tensioned to 28 kg for several different time intervals prior to clamping. Stiffness decreases with an increase in temperature and increases with a decrease in temperature. A warmer ball will bounce higher than a cold one. Knowing this can help your scores. Ever felt that muggy feeling when it is particularly humid outside? Overall the residual plots show that the fit is good, but there is some considerable doubt and, it is possible another model might fit the data even better. In order for maximum force to be generated, a tennis player needs a good stable base from where they can begin the movement. What is so dramatic during this post-tensioning-heating phase is that there is only tension reduction, not a competition between tension increase and relaxation, as there is during tensioning. Figure 3 Tension vs time for the same string as Figure 2 but following the heating-after-tensioning protocol. This act is attained underhand or overhead. Generally, temperature affects a ball's resiliency, the spin and the density of the air through which the ball travels. Energy Flow and Return Between a Tennis Ball and Stringbed, Free-standing vs Hand-held Racquet Testing. (Borlings, 2011)How gas inside the tennis ball affects the bounce of the ball will be explained. It uses a lot of muscle memory. Results for Setup #2 ‐ Elongation, Tension and Stiffness vs Temperature. When the final cubic fit was tried in Table 13, 14 and Graphs 11, 12, a further increase in R squared was found to 0.979 and 0.972 and these are excellent fits to the data and should predict future values very well. Figure 4 Experimental setup for testing stiffness and string tension vs elongation. This increased energy and movement results in a higher bounce. The conclusion for the two different ball types will show which is in fact is a better ball in each of the different situations.
