In the beginning we had Newton's Laws which introduced force as the fundamental entity of nature. Energy was understood as a derived concept, i.e. Energy = force x distance.(adsbygoogle = window.adsbygoogle || []).push({});

Later, however, there arose the formulations of LaGrange and Hamilton where energy is the fundamental entity, i.e. Force = -dV/dx, etc., where V is energy.

But putting all the mathematics aside, what is the fundamental entity? Is it force or energy?
