| Question | Answer |
| Average Speed | Total distance travelled / Total Time Taken |
| Acceleration | Change In Velocity / time taken |
| Change in velocity | Final Velocity - Initial Velocity V - U |
| Final Velocity V | U + at |
| Displacement S | (u+v)/2 * t |
| Density D | Mass / Volume M/V |
| Gravitational Potential Energy GPE | Mass * Gravity * Height mgh |
| Work Done | Force x Distance Fd |
| Power | Work Done / Time Taken |
| Efficiency eff | Useful Energy out / Total Energy In UEout / TEin |
| Kinetic Energy KE | 1/2 x mass x velocity(2) 1/2mv(2) |
| Acceleration a | ( 2 x Distance in m ) / Time(2) 2S/t(2) |
| Unbalanced Force F | mass x acceleration ma |
| Momentum P | Mass x Velocity mv |
| Impulse | Force x Time Ft |
| Moment M | Force x Distance Fd |
