Energy Skate Park

Recently we learned about kinetic energy (energy of motion).

A system of objects may also contain stored energy, also known as potential energy, depending on their relative positions. As you can see on the energy graph, an object has more potential energy if it is positioned higher. In other words, the skater has more potential energy at the top of the ramp.
