**Theory of Work, Power and Energy**

### Work is defined by the dot product of force and displacement

Where F = force active on a point, S = Displacement and

Power is defined by the rate at which work is done.

Energy is defined as capacity to do work. There are two types of mechanical energy

a. Kinetic Energy

b. Potential Energy

Kinetic Energy: It is defined as energy possessed by a body by its motion. If mass of body is m and speed is v then kinetic energy

K.E. = 1/2 mv

^{2}

Potential Energy is defined as the energy possessed by the body by its position and strain.

It can be defined for conservative force field only. In case of uniform gravity, potential energy is mgh m m=mass of body

h= height from reference level

Unit and Dimensions

Energy and work have same units. Power is measured at the rate at which work is done.
