Mechanical Energy

Energy in an object which can create some motion in the object is known as mechanical energy. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. There are two forms of mechanical energy that is kinetic energy (energy due to motion) or potential energy (energy due to the position). Mechanical energy of an object can be calculated as the sum of the kinetic energy and the potential energy of an object.
