Question

explain law of conversation of mechanical energy with an example​

Answer 1

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

Answer 2

Answer:

The principal of conservation of mechanical energy states that if a body or system is subjected only to conservative forces the mechanical energy of that body or system remains constant
