measuring mechanical energy, an object is considered as a whole, as it is stated by Isaac Newton in his Principia : "The motion of a whole is the same as the sum of the motions. Mechanical energy - energy in a mechanical form energy, free energy - (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs; "energy can take a wide variety of forms". as cited on "Student Resources in Context". As the ball is swung backwards using mechanical energy, potential energy is stored. Examples are energy released by fission and fusion. 129131 Rusk, Rogers. In an elastic collision, mechanical energy is conserved;.e. Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision. For example, a person doing push-ups is doing work by applying force to the floor.

Noun ( plural mechanical energies) (physics) The sum of the potential energy and kinetic energy of a body or system. Let's describe mechanical energy in more detail. It is defined as the object's ability to do work and is increased as the object is moved in the opposite direction of the direction of the force. An example of mechanical energy is a wrecking ball that is swung backwards away from a building. It may be considered as energy relating to temperature. If additional energy is supplied to the object, it actually increases that object's mass. United States the Lady With The Pet Dog by Anton Chekhov of America: University of California Press. The law of conservation of energy states that in an isolated system that is only subject to conservative forces, like the gravitational force, the mechanical energy is constant. On the other hand, it will have its least kinetic energy and greatest potential energy at the extreme positions of its swing, because it has zero speed and is farthest from Earth at these points.
