| WORK | ENERGY |
| Work is said to be done when a force produces motion | The capability to do work is called energy. |
| Work cannot be transformed from one form to the other. | Energy can be transformed from one form to another. |
| If an object doesn't move on applying force no work is said to be done. | If an object doesn't move on applying force even, then the energy of the body is consumed. |
| There is only one type of work which can be positive, negative, or zero | Energy can be of many types like Potential Energy, Kinetic energy, heat energy, chemical energy, etc. |
| Work done = force × displacement | Potential energy = m×g×h |
| By work-energy theorem: Work done = change in kinetic energy | Kinetic energy = \(\frac{1}{2}\)mv2 |
