An illustrative experiment on this issue

How can energy be transported in a hydraulic circuit? The volume of oil is nearly incompressible. Therefor energy can not be transported in the form of potential (inner) energy of the oil.

Two identical cars collide with equal and opposite velocity to each other. What happens to the energy? What happens to the momentum? Answer: energy is converted into heat and momentum disappears. But what has that to do with force?

On youtube I found a reference to systems physics . Does anyone know what systems physics is? Video:

In the impact, the spheres exchange momentum but no angular momentum. Therefore a slipping phase follows after the impact until the spheres can roll without friction. Hier you can find an explanation in German;
