at the bottom before he starts moving back up.
Top Left of Ramp: The graph is exactly the same as the top right of the ramp. With potential and
total energy at their maximum and the speed at zero.
3. Explain how the speed is connected to the energy values.
4. Switch to the friction simulation and leave the friction setting in the middle of the range. Turn
on the Bar Graph and Speed indicators. Place the skater back at the top of the ramp. Describe the
bar graph and speed by pausing the simulation at each of the following locations:
5. Discuss what happens to the skater over time in this case. Why does this happen? What kind
of energy is generated when there is friction present?
