Hallo everyone! energy in a physical system is the ability to do work. E=W Where Work = F x D Now if the force increase obviously "work" will increase! does that mean the energy also increases? Now if I had a system and the force in its start is 20 Newtons x 2 meters = 40J = The amount of energy in the system right? If the force increase to lets say 50 Newtons x 2 meters= 100J so its goes on and on and on and the energy is going to increase much much more right? So if force in a system's start at 20N then more forces is added the energy increase right? Hope I'm making sense! In a way im trying to say "energy" in a system can increase if "force" or "distance" increase right? Where both force and distance are the main valuables of the system. Thanks!
