The joule is a derived unit of energy or work in the International System of Units. It is equal to the energy expended (or work done) in applying a force of one newton through a distance of one metre (1 newton metre or N·m), or in passing an electric current of oneampere through a resistance of one ohm for one second.
The unit for work done is the joule (J).
The SI unit for work done on an object is the joule (J).
The unit of work done is the joule (J), which is also the unit for energy. This is because work done is the transfer of energy from one system to another. So, the unit for work done being the same as the unit for energy reflects the close connection between the two in the context of physics.
Work done per unit time is called power because power is work done divided by time in sec. So per unit time is seconds.
" power "
Watt is the unit that measures one joule of work done in one second.
Work per unit time is power. It can be thought of as rate of doing work.
It doesn't. (Any unit of force) times (any unit of distance) is a unit of work, and so is any other unit of energy. (By the way . . . 'meters' is not a unit of work.)
power
Work done is a measure of expended energy, so the SI unit for work done is the same as for energy - the Joule.
The amount of work done divided by the time it took to do the work equals the unit rate. w/t=unit rate
Work done per unit of time is defined as power. In the metric system, this unit is a watt. In the standard system, it is horsepower.
