Draw an energy flow (LOL Diagram) for each scenario before you attempt to solve.

 

1. How much potential energy is associated with a 2kg ball that is held in position at the top of an 8 meter- high ramp? With what velocity will this ball travel when it reaches the bottom of the ramp?

2. How much potential energy is associated with a 5kg ball that is held in position at the top of an 8 meter-high ramp? With what velocity will this ball travel when it reaches the bottom of the ramp?

3. What conclusions can you make about masses effect on potential energy? On velocity?
