Nucleons consist of quarks which are charged particles. Proton has the quark content of uud and neutron of udd. So, it may be visualized that the down quark always remain between the up quarks inside proton and the up quark remains between the down quarks inside the neutron. Are these quarks stationary inside protons or neutrons? (if yes, why and how is it so?) Or, the up quarks rotate around the down quark in proton and the down quarks around the up quark in neutron? (if so, do they move along the same orbit?)
Supposedly quarks are in a well but experience minimal or no force at close range, called asymptotic freedom. If it is assumed that a quark model can be used where they are treated as "Point" particles, then they should be like three particles in a well. If QCD is believed then they are in different "color" states so can be in the same particle-in-a-well ground states. This could still be true if "bag models" are used instead of QCD.
