- Thus, the potential of an object to come back to the ground when suspended freely is referred to as potential energy possessed by the object.
- When a spherical object is set free on an inclined plane, it automatically gains motion.
- As long as the object continues to roll down the inclination, it is said to have kinetic energy.
