The difference between energy and forces

  1. Dec 18, 2011 #1
    What is the difference between energy and the four fundamental forces. They both seem to move bodies, so what's the difference?

    Look at the math:

    work (energy expended) = force * distance

    Forces cause motion (namely, acceleration). Energies are quantities that objects have that are "conserved" when they interact with other objects. They are distinct quantities and concepts, though. An object can have forces acting on it, but have no change in energy. However, the converse is not true; an object can not have a change in energy without some force acting upon it.
