In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes. In all real systems… WebWhen work done on an object increases only its kinetic energy, then the net work equals the change in the value of the quantity 1 2 m v 2 .

WebAs discussed above, mechanical energy is the sum of potential and kinetic energy of an object. This sum always remains constant. The reason for the mechanical energy of an object to remain constant is that it does not increase or decrease based on external factors. But, it only depends on the physical properties of the object under consideration.

WebMechanical energy is energy stored in objects by tension. Compressed springs and stretched rubber bands are examples of stored mechanical energy. Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together.
