the energy an object has from its position or condition, like a ball on a hill or a stretched spring

The energy an object has from its position or condition, like a ball on a hill or a stretched spring

Potential energy

The energy an object has from its position or condition, like a ball on a hill or a stretched spring, is potential energy. Potential energy is stored energy that can make things move or change when it is released.

the distance an object travels per unit of time

The distance an object travels per unit of time
