Question

conservation of mechanical energy​

Answer 1

Answer:

mechanical energy is closed system in absence of dissipative forces eg friction air

Answer 2

Answer:

Mechanical energy is the sum of potential and kinetic energies in a system. In the principle of the conversation of mechanical energy states that the total mechanical energy in q system (i.e.,the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces
