Gravitational and Elastic Potential Energy
... The total mechanical energy of a system is the sum of its kinetic energy and potential energy. A quantity that always has the same value is called a conserved quantity. When only the force of gravity does work on a system, the total mechanical energy of that system is conserved. This is an example o ...

Work, Power, Energy
... The work done on an object by a constant force is the product of the force that is parallel to the displacement (θ = 0°) times the displacement. Work is computed by W = F × Δx × cosθ where F is measured in N, Δx is the displacement measured in m and θ is the angle between the force and the displacem ...
