nuclear force

A conservative force is defined as a force with the following property: when a particle moves in any closed loop, the force acting along the path multiplied by the distance travelled always sums to zero.
This is equivalent to saying that when an object moves from one location to another, the force changes the potential energy of the object by an amount that does not depend on the path taken.
The nuclear force is only felt among hadrons. At much smaller separations between nucleons the force is very powerfully repulsive, which keeps the nucleons at a certain average separation. Beyond about 1.7 femtometer (fm) separation, the force drops to negligibly small values.
At short distances, the nuclear force is stronger than the Coulomb force; it can overcome the Coulomb repulsion of protons inside the nucleus. However, the Coulomb force between protons has a much larger range and becomes the only significant force between protons when their separation exceeds about 2.5 fm.
The nuclear force is nearly independent of whether the nucleons are neutrons or protons. This property is called charge independence. It depends on whether the spins of the nucleons are parallel or antiparallel, and has a noncentral or tensor component. This part of the force does not conserve orbital angular momentum, which is a constant of motion under central forces.
Nuclear force is still a concern topic of research.
scientists are trying to find new and intresting thigs about the nucleus

conservative force is a force which haveproperty like: when a particle moves in any closed loop, the force acting along the path multiplied by the distance travelled always sums to zero.

The nuclear force doesnt fulfill all these criterias. it work at very smalll distances like b/w nucleons the force is very powerfully repulsive, which keeps the nucleons at a certain average separation. Beyond about 2fm separation, the force drops to negligibly small values.
At short distances, the nuclear force is stronger than the Coulomb force; it can overcome the Coulomb repulsion force of protons inside the nucleus. However, the Coulomb force between protons has a much larger range and becomes the only significant force between protons when their separation exceeds about 2.5 fm.
