AI Thread Summary
The discussion explores the relationship between energy and force, questioning whether energy originates from force or vice versa. It highlights the distinction between Newtonian mechanics, which focuses on forces, and Lagrangian/Hamiltonian mechanics, which emphasizes energy. The latter is noted for its application in quantum mechanics, suggesting it may be more fundamental. However, complexities such as friction present challenges in modeling energy without considering forces. Ultimately, the interaction between energy and forces remains a nuanced topic without a definitive answer.

does energy comes from force or force comes from energy.Which is more fundamental energy or force?

I am not sure that your question has a definite answer. Basically you can split classical mechanics into Newtonian analysis and Lagrangian/Hamiltonian analysis. The former uses forces, the latter uses energy. The Lagrangian/Hamiltonian approach is used in quantum mechanics, so you might say it is more fundamental. But there are situations, like friction, that are quite difficult to model that way. So it isn't obvious to me.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
