| Question | Answer |
| Efficiency (%) | Efficiency (%) = (Useful energy out/ total energy in)*100 |
| Gravitational Potential Energy (GPE) | GPE= Mass* gravity* height |
| Kinetic Energy (KE) | Kinetic Energy = 0.5*mass*velocity^2 |
| Work Done | Work done = Energy transferred |
| Power | Power= Energy/ Time |
| Energy | Energy= specific heat capacity * mass * change in temp |
| Speed | Speed=distance/time |
| Acceleration | Acceleration=change in velocity/time |
| Force | Force=mass*acceleration |
| Weight | Weight=mass*gravity |
| Momentum | Momentum=mass*velocity |
| Change in momentum | Change in momentum=force*time |
| Density | Density=mass/volume |
| Pressure | Pressure=force/area |
| Moment | moment=force*perpendicular distance from pivot |
| Velocity (waves) | velocity=frequency*wavelength |
