None of these quantities or relations involves time explicitly, yet we know that the time available to accomplish a particular amount of work is frequently just as important to us as the amount itself.

The instantaneous power of a constant applied force is the product of the component of the force in the direction of motion and the instantaneous velocity of the moving object.

If the power is constant over a time interval, the average power for that interval equals the instantaneous power, and the work done by the agent supplying the power is
