Question

state and prove the law of conservation of mechanical energy.​

Answer 1

Step-by-step explanation:

laws of the conversion of mechanical energy:

the total amount of mechanical energy, in a closed system in the absence of dissipative force remains constant

Answer 2

Answer:

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces. We could use a circular definition and say that a conservative force as a force which doesn't change the total mechanical energy, which is true, but might shed much light on what it means.
