Question

a skateboarder is standing at the top of a tall ramp waiting to begin a trip. the skateboarder has
kinetic energy only.
potential energy only.
both kinetic and potential energy.
neither kinetic nor potential energy.

Explanation:

Kinetic energy is energy of motion. Since the skate - boarder is standing still, there is no kinetic energy. Potential energy is stored energy due to position. At the top of the ramp, the skate - boarder has gravitational potential energy because of their height above the ground.

Answer:

B. potential energy only.
