Hallo, When force is acted upon a certain object it could change its direction,movement. Does force require energy to be produced? Looking at all the natural forces they seem to be created and force comes along with them. If force can move an object or stop an object or ever accelerate one. What is energy's role in all of them? Is it like this example: Magnetic fields producing a natural force that can only be triggered by energy, same as gravity. Are natural force only triggered by energy?
