Dear Student

Energy  can neither be created nor be destroyed but it can be transfered
from one form to another form. The total amount of energy in the
universe remains the same.

The same applies to an isolated object.

Usually we consider the Kinetic and potential energies .  So from energy concervation KE+PE=Constant
