Question

explain law of conservation of mechanical energy with examples​

Answer 1

In other words, it will not change (become more or less). This is called the Law of Conservation of 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).

this is the answer of your question please mark me brainleist please

Answer 2

Conservation of Mechanical Energy

The sum total of an object’s kinetic and potential energy at any given point in time is its total mechanical energy. The law of conservation of energy says “Energy can neither be created nor be destroyed.”

So, it means, that, under a conservative force, the sum total of an object’s kinetic and potential energies remains constant. Before we dwell on this subject further, let us concentrate on the nature of a conservative force.

Assume a pendulum (ball of mass m suspended on a string of length L that we have pulled up so that the ball is a height H < L above its lowest point on the arc of its stretched string motion. The pendulum is subjected to the conservative gravitational force where frictional forces like air drag and friction at the pivot are negligible.
