|---|---|
| Work done | force x distance |
| Kinetic energy | 0.5 x mass x (speed)^2 |
| Gravitational potential energy | mass x gravity x height |
| Power (in terms of work done or energy) | work done / time OR energy / time |
| Efficiency | useful output / input |
| Potential difference | current x resistance |
| Power (in terms of potential difference) | potential difference x current |
| Power (in terms of resistance) | (current)^2 x resistance |
| Energy transferred | charge flow x potential difference |
| Density | mass / volume |
