Bounce Lab
Bounce lab
Purpose: The reason why we did this lab was to see how much work the ball had to do when it hit the ground, how much energy is absorbed when the ball hit the ground, and how high it went after it bounced back up after hitting the ground.
Materials: One blue bouncy ball, a super ball, tape measure, table surface, and graph paper.
Procedures: See Q.S.L lab manual Pg. 10-13
Analysis: (1) One variable that can affect the lab is the different types of surfaces that you bounce the ball on because one surface mite absorb more of the force that the ball gives off when it hits the ground than another surface. Another problem that could be a benefactor is how you release the ball, your hand mite shake when you let the ball go and that could affect the balls rebound height.
(2) It shows me how both of the bouncy balls I used; they were very different in results. It shows me how each ball absorbed a different amount of energy when it hit the ground.
(3) If the balls were dropped from 87cm, they would both have different results than each other. Because looking at the graft, they both have a different rebound height, as I answered in question 3. If the rebound height would have to be about 83cm for the blue bouncy ball because it had to have a higher release height because it absorbed more of the bounce. The black super ball would have to have about 70 cm of a drop height because it absorbed less of the bounce so it would bounce up to 52cm or higher.
(4) If the bleu bouncy ball was released at 38cm, it would probably bounce up to 30 cm because the ball had a bigger mass it would bounce up to about the same height that you dropped it from. The black super ball would probably bounce only up to 20cm because the ball would need to have a higher drop height to bounce higher.
(5) The release height and the rebound height are very similar because they both have to do with how the ball absorbs the ground. You can relate this to the graph because it shows how much the ball absorbed when it hit the ground and how much the rebound height was.
(6) When you divide the release height by the rebound height it gives u a pattern because the all are consistent and going up as your release height gets higher.
(7) The similarities show how the balls have an increase of a rebound height as the release height gets higher.
