Power equals work divided by time. If work is in joules (J) and time is in seconds (s), power is expressed in joules/second, or the simplification watt (W). James Watt was a British scientist who invented the steam engine. To find out how the power of his engine compared to that of a horse, Watt measured how fast an average horse could do work.

WORK = _____ N.m = _____ Joules. The rate at which energy is transformed or the rate at which work is done is called POWER (P) and is defined as work per unit time, P = W/t. The unit is a Joule per second and is also called Watt (Though originally power was defined in HORSE POWER and units like ft. lb/sec).

(Remember Joules are a measurement of work. So the force (remember weight is a force) you moved multiplied by the distance that you moved it will give you the number of Joules. (Dividing the number of Joules by the amount of time (in seconds) it took you to do the work will give you power- in watts, which are Joules per second.
