to start skateboarding at position 1. The skateboarders are all the same
height and weight. Which skateboarder will have the greatest amount of
gravitational potential energy?
The skateboarder who took the stairs.
The skateboarder who skateboarded up the half-pipe.
The skateboarder who walked up the half-pipe.
O
The gravitational potential energy is the same for all of the
skateboarders.
