| Question | Answer |
| Distance Travelled = x = | Average Speed x Time s x t |
| Acceleration = a = | Change in Velocity ÷ Time Taken v - u ÷ t |
| Force = F = | Mass x Acceleration ma |
| Weight = | Mass x Gravitational Field Strength |
| Efficiency = | (Useful energy transferred) ÷ (total energy supplied) |
| Momentum = | Mass x Velocity |
| Wave Speed = | Frequency x Wavelength |
| Wave Speed (2) = | Distance ÷ time |
| Density = | Mass ÷ Volume |
| Work Done = | Force x Distance Moved in Direction of Force |
| Change in Gravitational Potential Energy (GPE) = | Mass x Gravitational Field Strength x Change in Vertical Height |
| Kinetic Energy = | 1/2 x Mass x (Speed)² |
| Power = | Work Done ÷ Time Taken |
| Energy transferred = | Charge Moved x Potential Difference |
| Charge = | Current x Time |
| Potential Difference = | Current x Resistance |
| Power (2) = | Energy Transferred ÷ Time Taken |
| Electrical Power = | Current x Potential Difference |
| Electrical Power (2) = | Current ² x Resistance |
| Force Exerted on a Spring = | Spring Constant x Extension |
| Moment of a Force = | Force x Distance Normal to the Direction of the Force |
| Pressure = | Force Normal to Surface + Area of That Surface |
