Question

state the law of conservation of mechanical energy

Answer 1

the law of conservation of mechanical energy states that mechanical energy cannot be destroyed but can be converted from one form to another. the sum of all the energies of a system always remains constant.

Answer 2

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of theconservation of mechanical energy states that the totalmechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.
