the ability to do work
Type of energy an object has because of its position or condition.
potential energy
What happens to the potential energy of a ball as it falls from a height, and what type of energy does it gain?
The potential energy decreases as it falls, and it gains kinetic energy.
When an object is not moving, it has little to no what type of energy?
kinetic energy
