| Question | Answer |
| Speed Distance Time | Speed= Distance / time |
| Acceleration Time taken Change in Velocity | Acceleration = Change in velocity / Time |
| Weight Gravitational Field Strength Mass | Weight = Mass x Gravitational Field Strength |
| Force Acceleration Mass | Force = Mass x Acceleration |
| Thinking distance Stopping distance | Stopping distance = Thinking distance |
| Momentum Mass Velocity | Momentum = Mass x Velocity |
| Force acting Change in momentum Time taken for change to happen | Force = Change / time |
| Total anticlockwise moment Total clockwise moment | Total anticlockwise moment = Total clockwise moment |
| Electrical power voltage current | Electrical power = current x voltage |
| Energy transferred voltage current time | Energy transferred = voltage x current x time |
| voltage resistance current | voltage = current x resistance |
| Charge current time | charge = current x time |
| wavespeed Frequency wavelength | Wavespeed = Frequency x wavelength |
| angle of incidence angle of reflection | angle of incidence = angle of reflection |
| refractive index speed of light in a vacuum speed of light in that material | refractive index = speed of light in a vacuum / speed of light in that material |
| sin c n | sin c = 1 / n |
| efficiency total input useful output | efficiency = Useful output / Total input |
| power time work done | power = work done / time |
| work done distance moved force | work done = distance moved x force |
| Kinetic energy mass speed | Kinetic energy = 0.5 x mass x speed(2) |
| GPE Mass Gravitational field strength height | GPE = mgh |
| density volume mass | density = mass / volume |
| pressure area force | pressure = force / area |
| pressure difference g density height | pressure difference = height x density x g |
| constant temp pressure volume | temp = pressure x volume (p1V1 = p2V2) |
| constant vol temp pressure | vol = pressure / temp (k) (p1 / T1 = p2 / T2) |
