Work, Paper, Efficiency:
Work, is the enegy transferred by applying a force on an object over a distance. But when a work is a negative value. When the object is moving, it means that the force is acting in two opposite direction as it is moving. Which means that the force is taking energy away from the light.
Power, is the rate which work is done on a object. Machines are used to put work power to it, and you combined the machine together with the power, and it makes the machine work. Sometimes the machine can have an electrical occurance and it can cause a short circut and will eventually damage the machine.
Percent efficiency of a machine is the ratio of the work output to the work input. It explains how much energy the machine needs to work as a adpated to the energy.
