Force concept,is it different in Quantum Mechanics than in Relativity Theory?

Answer 1

They don't seem to talk much about force in quantum mechanics. All they talk about is energy. And that energy is quantized, meaning it cannot have just any value, so a graph of increasing energy would be a stair step line instead of a slanted straight line. I guess you could relate force to energy, even in quantum mechanics, and if you did, force would have to be quantized too. That would mean that only specific values of force were allowed, with no values in between those allowable values being possible. In comparison to that, relativity is just classical mechanics with a small correction that grows large for very high speed cases.

Answer 2

In physics, energy is a much more useful concept than force. You can actually derive much of classical mechanics without using the classical concept of force. In physics, we talk about four fundamental interactions (forces). They are all conservative, meaning that you can understand them in terms of how their corresponding potential energies various with space. Since energy is a more fundamental concept, we look only at the energy, not forces, whenever we can. This way of looking at forces is the same whether you are dealing with classical physics, relativity, or quantum mechanics.

Answer 3

Don't mix up dude force has nothing to do in Quantum mechanics.

Answer 4

Yes they are different and recent research into slice thoeries may hold the key to their relationships
