| Question | Answer |
| Gas law | Pressure x volume = constant |
| Charge and current | charge = current x time |
| Thermal capacity | Thermal capacity = mass x specific heat capacity |
| Power | Power = current x voltage |
| Critical angle | N = 1 / Sin(c) |
| Changing state energy | Energy change = mass x latent heat |
| Wave speed | Wave speed = frequency x wavelength |
| Ohms law | Voltage = current x resistance |
| Pressure | Pressure = force / area |
| Specific heat capacity | Thermal energy change = mass x specific heat capacity x change in temperature |
| Snells law | N = Sin(i) / Sin(r) |
| Fluid pressure | Pressure = density x gravity x height |
| Half life | Time taken for half a radioactive sample to decay |
| Gravitational potential energy | Gravitational potential energy = mass x gravity x height |
| Hooke's law | Force = Spring constant x extension |
| Impulse | Change in momentum = Force x time |
| Range of human hearing | 20 to 20,000 Hz |
| Distance time graph area | Area = distance travelled |
| Diffraction | The spreading out of waves as the pass through a gap |
| Speed of light | 3 x 10 to the power of 8 m/s |
| Mechanical power | Power = Energy / time |
| Electrical energy | Energy = current x voltage x time |
| Transformer equation | (Primary voltage / Secondary voltage) = (Primary no of coils / Secondary no of coils) |
| 100% efficient transformer equation | Current (P) x Voltage (P) = Current (S) x Voltage(S) |
| Distance time graph gradient | Gradient = Velocity |
| Average speed | Speed = Distance / Time |
| Velocity time graph gradient | Gradient = Acceleration |
| Kinetic energy | Kinetic energy = 1/2 x mass x velocity squared |
| Newton's second law | Force = Mass x Acceleration |
| Acceleration | Acceleration = Change in velocity / time |
| Efficiency | Efficiency = Useful output x 100% / Total energy input |
| Turning moment | Moment = Force x perpendicular distance |
| Weight | Weight = mass x gravity |
| Work done | Work done = Force x Distance |
| Momentum | Momentum = mass x velocity |
| Density | Density = Mass x volume |
