Problem: How can the potential energy of a dropped ball be increased?

Hypothesis: If _______________________________________________________________________________,

then _______________________________________________________________________________________.

Procedure:
1. Starting at the floor, stretch the tape vertically against the wall or table leg.
2. Draw lines across the tape to mark ½ meter (50cm), ¾ meter (75cm), and 1 meter (100 cm) above the floor.
3. Hold the ball at the ½ meter mark and drop it. Observe carefully as the ball bounces.
4. Mark the height of the bounce on the tape.
5. Use the meter stick to measure the height of the bounce and record it in the data table.
6. Repeat steps 3-5 for a total of 3 trials.
7. Hold the ball at the ¾ mark and repeat mark and repeat steps 3-6.
8. Hold the ball at the 1 meter mark and repeat steps 3-6.
