WebbPower is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. Power = Work / time or P = W / t The standard … WebbLifting a rock up off the ground is work because the rock is moving in the direction that force is applied. The last example is less obvious. Recall from the laws of motion that force is not required to move an object at constant velocity.
