Energy neither created nor to be destroyed but it is a form of energy according to principle of the law of conservation of energy.

Principle of conservation states that energy neither be created nor destroyed but transfers from one form to another.

Law of conservation of energy: Energy is neither created nor destroy but its can be change one form to another form.

If it is vacuum then external force is required to stop.

If not at some point the body goes to the rest position.

According to principle of energy conservation do not destroy the energy, energy changes one phase to other phase.

The question related to the Newtons Second law of motion, whereas the law of conservation of energy is different.

Here, there may be variation of air resistance and road evenness for that, it would change its momentum.
