Ball bounce higher when it is warmed up Essay

Prediction I predict that for this taste the higher the temperature, the more than the dinner dress ordain bounce. I put this down to the temperature is raised, the particles inside will gain energy in that respectfore the higher the ball will bounce. Equipment For this sample I will use the following equipment to do this experiment 1. Beaker 2. Bunsen burner 3. Splints 4. Tripod 5. netting 6. Thermometer 7. Squash Ball 8. Paper Towels 9. Meter Ruler 10. Tongs 11. Stop Clock 12. Safety goggles. regularity Choose one yellow spot quell ball.This will be used through aside the experiment to ensure that the ball is made of the same rubber and same size. The experiment will be carried out on the hard floor tiles of the science laboratory. The area will be clean to ensure there are no irregularities on the surface. The ball will be heated to the required temperature by placing it in a beaker of heated water for one minute. To ensure the human body does not affect the temperature, tongs will handle it. temp (? C) Temp (Kelvin).Results I am going to subject field out draw and predicted cling magazine using the following formulas. This is how to work out pressure P1 is Pressure 1, which is al behaviors 1. T1 is judgment of conviction 1 and T2 is Time 2. This number c bent grasses as you work out To work out predicted hang duration you use this formula. In this formula P1, P2 etc are Predicted hang time. This number changes as you work out Temp (Kelvin) Pressure Predicted Hang time Actual Hang time.Analysis From my graph I can suffer that the predicted hang time and the literal hang time differ greatly from 293 Kelvin onwards, the real hang time increases quite dramatically where as the predicted hang time escalates only a bit. From doing this experiment I have found out that when pressure is increased by raising the temperature inside a hale ball, the particles gain more energy and can correct more quickly from its impact on the surface.My actual hang time resolutions show this. My prediction was correct in the sense that my theory of the particles gaining energy worked. My predicted hang times unfortunately were not correct. They were not a good match to my actual hang time results I put this down to another variable. The other variable I believe is shot of the squash balls material. I believe that if the ball has high elasticity then the deformation (formed by the impact of the ball hitting the surface) of the ball will be bigger and because it is bigger it will tame more quickly and bounce higher.The energy at the start of the dropping process gravitative emfity energy, but as the ball speed increases this changes to kinetic energy. When the ball reaches impact, kinetic energy changes to elastic potential energy and a bit of thermal and sound energy. This thermal and sound energy remain at a low constant throughout the rest of the balls bounce back. When the ball reforms it bounces up and gravitational energy increases to its previous level. Evaluation I think I conducted my experiment to a high bar and there were no major anomalous results (except the hang time and predicted hang time results).Each result had an average difference of 7. 9 between the next one, this average was brought down drastically by the 2. 8 difference between the first two results (38. 4 and 41. 2). If I were to make any improvements to the method and equipment of this experiment I would 1. Change the way the ball was dried as I think a more sophisticated way could be used to prevent human error. 2. Use a different way of timing the balls impact to the ground a touch sensitive timer mat would work well. 3.I would try different surfaces on which the ball lands on, this could be thought of as another variable I could develop. If I were to do this experiment I would change the temperatures to smaller differences i. e. 273 Kelvin, 278 Kelvin etc. to see if I could find an ideal temperature that had a good enough bounce to hel p develop work into elasticity of the balls material. If I were to develop this experiment further I would test elasticity. To test this I would experiment with a range of different squash balls.I would cut them into equal narrow pieces and use a nitrogen spring to test how much the piece of squash ball could hold and how long it would take to reform back to its original shape, for this I would use a Newton spring and stop clock. All in all I think I conducted myself well on this experiment and have learned a lot.
