| Question | Answer |
| Efficiency | Eff=UEO/TEIx100% |
| Kinetic Energy | halfxMassxVelocitysquared |
| force | mass x acceleration |
| gravitational potential energy | mass x gravity(10) x height |
| work done | force x distance |
| power | work done/time |
| acceleration | final velocity - initial velocity divided by time |
| weight | mass x gravity |
| displacement | half(initial velocity-final velocity)time |
| hookes law | spring constant x extension |
| energy forms | light, kinetic, electro magnetic, thermal, elastic, chemical, gravitational, nuclear, sound |
| resources(renewable) | tidal, biomas, wind, wave, geothermal, hydroelectric, solar |
| law of conservation of energy | energy cannot be created or destroyed, only changed in form |
| hookes law | the extension of a spring is directly proportional to the load, provided the elastic limit of the spring is not exceeded |
| what is a force | A force is a push or a pull |
