Question

law of conservation of mechanical energy formula​

Answer 1

Also, If conservative forces do the work in a system, the system loses potential energy equal to the work done. Hence, Wc = -PE. ... This law applies only to the extent that the forces are conservative in nature. The mechanical energy of the system is defined as the total kinetic energy plus the total potential energy.

Answer 2

Answer:

If you know the potential energies (PE ) for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is: KEi+PEi=KEf+PEf KE i + PE i = KE f + PE f
