Safari BJ'KH 4:50 7B 20 E Energy Loss VIRTUAL LAB (updated Mar 2021) Energy of a Dropped Ball Virtual Lab 180/0 Name: Thinking OBJECTIVES 116 Communication Determine the relationship between height and gravitational potential energy. Determine how the drop height (gravitational potential energy) of a ball affects the bounce height (kinetic energy) of the ball MATERIALS Virtual Forces Lab simulation https://www.theph.ysicsaviary.com/Phy_sics/Programs/Labs/Energy.LossLal Graphing Software http://www.thephysicsaviary.com/Physics/Programs/Tools/Graphing/ind PRELIMINARY QUESTIONS (Thinking) For each question, consider the motion of a ball dropped straight down, starting just before the ball is released to just before it reaches the final height after a bounce. Assume that there is very little air resistance. 1. 2. 3. What form(s) of energy does the ball have right before it is dropped? (1 mark) What form(s) of energy does the ball have while in motion near the bottom of its path? (1 mark) If there are no frictional forces acting on the ball, how do you expect the change in the ball 's potential energy to be related to the change in kinetic energy?
