Particle interactions are changes in the nature, number, or state of several particles, usually at a specific space-time point, underlying dynamics. They are represented by special "field interaction terms" in quantum field theory and normally entail interchanges of energy, momentum, and sundry quantum numbers. They include scattering, and particle creation and annihilation.

Why do atoms repel when closer but attract when farther apart?
In real life there are frictional interactions that would make this system to damp, so the ball finally gets to a static situation on the equilibrium point (the lower part of the valley). …

How exactly is a normal force exerted, at the molecular level?
So we can avoid calculating billions of interactions because the reality is that this is just a wave propagating downwards (more like a pulse but still a wave). … These interactions become background noise vibrations, and these vibrations is what we perceive, as macroscopic beings, as the temperature of the object. There is no damping. …
