| Question | Answer |
|---|---|
| W= | Fs |
| GPE= | mgh |
| 1 joule= | N-m Ft*pound kg*m/s^2*m kg*m^2/s^2 |
| KE | =mv^2/2 |
| unit of work | joule |
| unit of KE | i joule or kg* m^2/s^2 |
| PE= | mgh |
| KE= | TE-PE |
| power= | work over time |
| standard unit of power | Watt,w |
| watt= | joule/second |
| one horsepower= | 746 watts |
| power is also | work * displacement / time |
| power is also w*d/t or | force * velocity |
| find kilowatt | mgh/t |
| conversion of kw to hp | kw*1/746 |
| upward force | bouyant force |
