Work, Energy and Power

If you push a brick wall until you sweat, physics says you have done absolutely zero work.

Work only happens when a force actually moves an object. We calculate it by multiplying the force applied by the distance moved in that direction.

Energy is simply the stored capacity to do this work. When you lift a heavy box, your muscles transfer chemical energy into gravitational potential energy.
