Procedure a one 1. Select a hard surface that will not be damaged by dropping each ball from a meter (h = 1 m) height. For better result, you can set and tape the wooden meter stick flat on the ground next to a wall or table. Make sure that the meter stick starts with 0 is at the bottom. 2. Drop each ball in the same height h, and record the height to which it rebounds h'. 3. Repeat five times for each ball and record the measurement on the data table 1. 4. Increase the height, h to two meters (h= 2m). Drop the baseball ball and record the height to which it rebounds h'. 5. Repeat five times for baseball ball and record the measurement on the data table 2.
