Answer:
A body possess kinetic energy by virtue of its motion. It is given by:
[tex]K.E. = \frac{1}{2}mv^2[/tex]
where m is the mass and v is the speed.
A body possess potential energy by virtue of its position.
Gravitational potential energy is given by:
G.P.E. = m g h
where m is the mass, g is the acceleration due to gravity and h is the height.
The sum of kinetic energy and potential energy is known as mechanical energy.
