Question

prove the total mechanical energy conserved under conservative energy ​

Answer 1

Answer:

If only internal force is doing work (no work done by external force)then there is no change in total amount of mechanical energy. Total mechanical energy said to be conserved.

Explanation:

Therefore for every displacement of delta X ,the difference between the sum of an objects KINETIC ENERGY and POTENTIAL ENERGY is zero.

In other words, the sum of an objects KINETIC ENERGIES and POTENTIAL ENERGIES is constant under a conservative force .

hence,the conservation of mechanical energy is proved.
