Question

law of conversatation of mechanical energy show by some example​

Answer 1

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

Answer 2

The sum of the gravitational potential energy and kinetic energy is called the mechanical energy. For example, in the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved).
