When work is done on an object, energy is transferred.
Energy transferred = work done, and so we can also say:
Power is the amount of work done in one second.
Power is measured in watts (W).
Power can be calculated using either of these equations:
|power =||power =|
|power in watts (W)||power in watts (W)|
|work done in joules (J)||energy transferred in joules (J)|
|time in seconds (s)||time in seconds (s)|
work = power x time taken
time taken =
