Two students are watching a person riding a skateboard up and down a ramp. Each student shares what they think about the energy of the skateboarder as they ride up and down the ramp. Elisa: I think the skateboarder has the more total energy at the top bottom of the ramp than the bottom of the ramp.

Raymond: I think the skateboarder has the same total energy at all points on the ramp.

Which student do you agree with? Why? In your response, include the following terms: total energy, kinetic energy, potential energy, height, mass, gravity and velocity.
