Question

The mechanical energy is conserved, when:​

Answer 1

Answer:

In an elastic collision, mechanical energy is conserved – the sum of the mechanical energies of the colliding objects is the same before and after the collision. After an inelastic collision, however, the mechanical energy of the system will have changed.only internal forces are doing work (no work done by external forces), then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved. ... In these situations, the sum of the kinetic and potential energy is everywhere the same.

Explanation:

Mechanical energy is not always conserved.

Mechanical energy is the sum of kinetic and potential energy in a system. Mechanical energy is conserved so long as we ignore air resistance, friction, etc.
