Power and units 


Force
= a push or Pull
measured in
Newtons
Work = Force over a Distance measured in Joules ( other wise called energy or Newton meters) Power = the rate at which Energy is used measured in Watts
In electrical terms power is rated in watts and
some motors are still rated in horse power (HP)
1000 watts = 1
Kilowatt kW
1000 volts =
1 kilovolt (kV) not likely to encounter this
in electronics
