The person has the greatest potential energy at the top of the ramp before they begin moving down into the ramp. Potential energy is determined by the height of an object in a gravitational field. The higher the object (in this case, the person on the skateboard), the greater the potential energy. When the person is at the top of the ramp, they are at the highest point relative to the bottom of the ramp, and therefore, their potential energy is maximized. As they descend into the ramp and move towards the lowest point, their potential energy decreases and is converted into kinetic energy (the energy of motion).
