Bouncing!
The purpose of this part of the lab was to recreate when someone releases a ball from a specific altitude, what happens? It bounces! But the bounce does not continue forever, friction and other factors take an amount of energy which decreases the initial velocity as the ball/square reaches the bottom and bounces, this is decreased each time the altitude is reduced. Another factor present here is the gravity or acceleration which adds more speed or velocity to the ball/square as it goes down and less as it goes up.
