Power is the rate of work that is done per time. Work is calculated from the product of force and the displacement. So, by using the definition of power and work, we can relate power with force, displacement and the time. We do as follows:
Power = Work / time
Power = Force x displacement / time
Power = 21 N (9 m) / 3 s
Power = 63 J /s = 63 W
There are two qualities that can describe most variables - direction and magnitude. A vector possesses both a direction and magnitude, while a scalar possesses only a magnitude.
