Question

Energy or Force..Which is more fundamental?

Answer 1

Please tell me the reason behind your answer..

Answer 2

Speaking in terms of classical physics, so not talking about the four fundamental forces of nature, for a force to act or be applied a mass is required so due to Einsteins Mass-Energy equivalence \[e=mc{^2}\]
energy is equivalent to mass. Therefore energy is more fundamental than force because force requires mass and mass requires energy.

Answer 3

Force...?

Answer 4

Of course energy! Energy is in fact the most fundamental concept in physics. Everything builds on our understanding of what energy is. Force is defined to be the change of momentum with respect to time. Momentum is thus more fundamental because force is defined in terms of momentum. But momentum is highly connected to energy, for example, through the relation P^2/2m=K . Therefore energy is more fundamental.

Answer 5

Actually, the answers seem to be equal. You need energy for an applicable force; however, without a force from that energy you have no means of measurement; therefor it doesn't exist because there is no force interacting upon the energy.

Now, energy is defined as how things get done; and force is what gets those things done. They are both very fundamental and equally important.
