The Effect of Air Pressure on a Basketball's Bounce
Transcript of The Effect of Air Pressure on a Basketball's Bounce
bounce higher when the pressure inside is greater. We think that when we start releasing air from the ball that it will not bounce as high. Materials - A ladder
-An air pressure gauge
-Vernier physics app on iPod
-Tape Procedure -a measurement chart was placed as a background for the experiment on the wall
- lines were measured and placed on the paper with paint every 10cm or 0.010m
-the basketball's pressure was then measured with an air pressure gauge and recorded
-one person climbed the ladder with the basketball while the other held the iPod to record the experiment.
-The person standing on the ladder held the basketball at arms length and dropped it at the same recorded height each time while the other videotaped the process
-This was repeated for 9 different trials of pressure levels. Air Pressure (psi) Question Will the bounciness of a basketball increase or decrease with a change in the air pressure? Will it affect the height of the bounce of the ball? Sources of Error - measurements of first bounce may not have been completely accurate
- data tables from the Vernier Physics app are false because of the angle of the iPod
- height of dropped ball may have been changed
- when taking the pin from air pump out of the basketball, excess air may have been released so amounts shown may not be accurate Acknowledgements Thank-you to:
