Terms | Definitions |
|---|---|
 Force | = mass x acceleration |
| Weight | = mass x gravitational field strength |
| Speed | = distance / time |
| Distance | = speed x time |
| Acceleration | = change in velocity / time taken |
| Average Speed | = distance traveled / time taken |
| Moment | = force x distance from pivot |
| Power | = current x voltage |
| Energy Transferred | = force x distance |
| Energy Transferred (electrical) | = current x voltage x time |
| Voltage | = current x resistance |
| Charge | = current x time |
| Wave Speed | = wavelength x frequency |
| Frequency | = 1 / period |
| Refractive index | = sin (angle of incidence) / sin (angle of refraction) |
| sin (critical angle) | = 1 / refractive index |
| Efficiency | = useful energy output / total energy input |
| Gravitational Potential Energy | = mass x gravitational field strength x height |
| Kinetic Energy | = 1/2 x mass x velocity squared |
| Power | = work done / time taken |
| Density | = mass / volume |
| Pressure | = force / area |
| Pressure difference | = gravity x density x height difference |
| pressure 1 x volume 1 | = pressure 2 x volume 2 |
