Term | Definition |
---|---|
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 |
