Question

What do you understand by the conservation of mechanical energy? State the condition under which the mechanical energy is conserved.

April 24, 2024

Answer

Whenever there is an interchange between the potential energy and kinetic energy, the total mechanical energy remains constant. This is principle of conservation of mechanical energy.

i.e K + U = constant provided there are no frictional forces.

The condition for mechanical energy to be conserved is that there should be no frictional forces. This condition is only applicable in vacuum.
