In this lab two carts will undergo elastic collisions, inelastic collisions, and explosions on a Vernier Dynamic Track. When does the ball have the most kinetic energy? The major finding was the return bounce height depended the most on the balls mass and from where it was dropped. In conclusion a basketball may look sample but its is very complex and can be very hard to manage. This is most likely because the reading of the return bounce was not exactly correct and neither was the drop height. Also, to see how gravity pulls the ball down storing energy and releasing the energy as the ball hits the bottom of the ramp and to see the distance the ball travels after books are added.
