| Formula | The energy stored in an object due to its position and height is known as potential energy and is given by the formula: P.E. = mgh |
| Unit | The SI unit of energy is Joules (J). |

How do you calculate work force and energy?
Work is the force exerted on an object times the distance over which the force is exerted: W = Fx, where W is the work in Nm = Joule. Work done to lift an object of mass m a height h: W = Fgh = mgh. Work done against friction: W = Ff x. Energy is the quantity that can be used to perform work.
How is work done related to energy?
Work and energy Work is closely related to energy. The work–energy principle states that an increase in the kinetic energy of a rigid body is caused by an equal amount of positive work done on the body by the resultant force acting on that body.
What is the relationship between work and potential energy?
Potential energy and work done are the same thing as much as kinetic energy and work done are the same thing. Potential energy is a state of the system, a way of storing energy as of virtue of its configuration or motion, while work done in most cases is a way of chaning this energy from one body to another.
What is the relationship between work force and energy?
Ans. The relationship between work and Kinetic Energy, also called the Work-Energy theorem, states that the work done by the sum of all the force acting over any particle/ object is equal to the change in the Kinetic Energy of the particle.
Is work done energy?
Work done has the same units as energy – joules. This is because energy is the ability to do work. So you must have energy to do work. Work done is equal to energy transferred.
