Potential energy?
Stored energy example gravitational potential energy
Kinetic energy?
The energy an object possesses are the results of Motion
Gravitational potential energy?
The energy an object has because of its position in the gravitational field relative to a reference point.
Mechanical energy?
The sum of the gravitational potential energy and kinetic energy
The law of conservation of energy?
In an isolated system energy can’t be created or destroyed it can only be transferred from one place to another.
The law of conservation of mechanical energy?
