| Energy | the ability to cause change |
| Kinetic energy | the energy due to motion |
| Potential energy | stored energy due to interactions between objects or particles |
| Work | energy transfer to an object by a force, making the object move in the direction of the force |
| Mechanical energy | the total energy of an object or group of objects due to large-scale motions and interactions |
| Sound energy | carried by sound |
| Thermal energy | sum of kinetic and potential energy of the particles in matter due to their random motion |
| Electric energy | carried by an electric current |
| Radiant energy | carried by electromagnetic waves |
| Nuclear energy | stored in the nucleus of an atom |
| Law of conservation of energy | energy cannot be created or destroyed, it is transformed into other forms |
