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 |
