Interpretation Introduction

Interpretation:

The perpetual motion machine and the non-existence of such device are to be explained.

Concept introduction:

Perpetual motion is defined as the motion of bodies that continues indefinitely. A perpetual motion machine is a hypothetical machine which can work indefinitely without an energy source.

The power that arises by utilizing the chemical or physical resources for providing heat and light or carrying out various processes is known as energy. The SI unit of energy is joule.

The law of conservation of energy states that energy can neither be created nor be destroyed, it can be converted to other forms.
