| Question | Answer |
| Speed | Speed = Distance / Time |
| Distance Travelled | Distance Travelled = Average Speed x Time |
| Acceleration | Acceleration = Change in Velocity / Time Taken |
| Force | Force = Mass x Acceleration |
| Weight | Weight = Mass x Gravitational Field Strength |
| Efficiency | Efficiency = Useful Energy / Total Energy |
| Momentum | Momentum = Mass x Velocity |
| Wave Speed | Wave Speed = Frequency x Wavelength or Wave Soeed = Distance / Time |
| Density | Density = Mass / Volume |
| Work Done | Work Done = Force x Distance (moved in the direction of the force) |
| Change in Gravitational Potential Energy | Change in Gravitational Potential Energy = Mass x Gravitation Field Strength x Change in Height |
| Kinetic Energy | Kinetic Energy = 1/2 x Mass x Speed squared |
| Power | Power = Word Done / Time Taken or Power = Energy Transferred / Time Taken |
| Energy Transferred | Energy Transferred = Charge Moved x Potential Difference |
| Charge | Charge = Current x Time |
| Potential Difference | Potential Difference = Current x Resistance |
| Electric Power | Electric Power = Current x Potential Difference or Electric Power = Current squared x Resistance |
| Force Exerted on a Spring | Force Exerted on a Spring = Spring Constant x Extension |
| Moment of a Force | Moment of a Force = Force x Distance (normal to the direction of the force) |
| Pressure | Pressure = Force (normal to surface) / surface area |
