Mechanical Power:

In the illustrations shown by Figure, the object obtains potential energy whenever it is lifted, and this potential energy is transformed to kinetic energy as the object falls (if it is permitted to fall). The final burst of sound, shock waves, and possibly outlying shrapnel is the last of the kinetic energy impart to the object by lifting. Where does the power fit into this scenario?

Figure: Example of power. A winch and pulley can be used to lift a heavy object.

A small variation on this theme can be used to chat about power. This is shown by the above figure Assume that rather of a free end of rope, you have a winch which you can turn to increase the object at the other end of the rope. The object begins out sitting on the floor, and you crank the winch for the reason of lifting the object. This, probably in conjunction with a complicated pulley system, will be essential if you have a heavy object to lift. Then the pulley had better be strong! The similar holds true for the rope. And let us not forget about the manner in which the pulley is anchored to the ceiling.
