Power = Energy / Time. So, both Kinetic and Potential contribute to power. Another expression for power= force x velocity, as energy and workd are basically sane, and work =force x displacement. read more
Work-Energy Principle. The change in the kinetic energy of an object is equal to the net work done on the object. This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. read more
Potential and kinetic energy are the two types of mechanical energy. An object stores potential energy and expends it as kinetic energy when it is in motion. Potential energy generally involves an object's potential for movement as a result of its place within the gravitational field of the Earth. read more
