QUESTIONS AND PROBLEMS:
1. What is the percentage error on each of the velocities in
your experiment? Discuss what could have caused this error.
2. How is the loss in the kinetic energy manifested by the
ball each time it reaches the ground?
3. In your experiment, calculate the kinetic and potential
energies when the ball was on its midway down the first, the
second, and the third time. What can you conclude about the total
mechanical energy of the...
