Why does a freely falling apple and the earth attract each other have potential energy? Why is it said that the parts of a compressed spring repel each other and have potential energy?

I think that having potential energy means that the system is not yet stable. They have the ability to independently recover to a state without potential energy. They attract each other, which means that they will continue to recover.

The second question is the same. They are also mutually exclusive and have the ability to continue to return to no potential energy, that is, with potential energy.
