Conservation of mechanical energy is defined as (a) Energy of motion

(b) Law of conservation of energy

(c) The sum of the kinetic and potential energies of an object remain a constant value unless there are forces acting on the object that cause a loss of energy overall, such a friction and air resistance.

(d) Potential energy added to kinetic energy
