Question

What do u understand by conservation of mechanical energy?

Answer 1

The potential energy, U, depends on the position of an object subjected to a conservative force. ... The principle of conservation of mechanical energy states that if a body or system is subjected only to conservative forces, the mechanical energy of that body or system remains constant.

Answer 2

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical 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.

hope helps ☺️☺️
