What do you mean by conservation of mechanical energy? State the condition when it holds?

Answer 1

Mechanical energy is the sum of Potential Energy and Kinetic Energy.

The only condition under which mechanical energy is conserved is that all the forces acting on it should be conservative forces.

Answer 2

Answer:

Mechanical energy is the sum of potential energy and kinetic energy.

The only condition under which Mechanical energy is conserved is that all the forces acting on it should be conservative forces.
