- 3momentum =mass x velocity
- 4work done =force x distance (along the line of action of the force)
- 5power =work done ÷ time
- 6efficiency =output energy transfer ÷input energy transfer
- 7gravity force =mass x gravity constant (g)
- 8in a gravity field: potential energy =mass x height x gravity constant (g)
- 9force exerted by a spring =extension x spring constant
- 10moment of a force =force x distance (normal to direction of the force)
- 11distance travelled =speed x time
- 12acceleration =change in velocity ÷ time
- 13wave speed =frequency x wavelength
- 14charge flow =current x time
- 15potential difference =current x resistance
- 16power = potential difference x current =\[current^2\] x resistance
