Question

what do you understand by the conversation of mechanical energy ?state the condition under which the mechanical energy is conserved.​

Answer 1

We know that neither can en eget be created nor can it be destroyed. It can only be converted from one form to another.

Here, mechanical energy is changing to another form of energy.

For eg. dynamo(or generator) , here if the axle is rotated , the mechanical every used to rotate itself converts into electrical energy.
