sum of kinetic energy and the potential energy
The sum of the kinetic energy and the potential energy is known as the mechanical energy.
The energy of a body possessed by the body by virtue of its position or configuration is called the potential energy of the body.
The formula for the potential energy is given by
U = m x g x h
where, m is the mass of the body, h be the height of the body and g be the acceleration due to gravity.
The energy of the body possessed by the motion of the body is called its kinetic energy. The formula for the kinetic energy is given by
K = 0.5 x m xv^2
