What’s the other 4? Gravity… and… Light? Kinetic? Magnetic?
- Strong nuclear force: holds the nucleus of an atom together
- Weak nuclear force: responsible for radioactive decay
- Electromagnetic force: of charged particles
- Gravitational force: attractive force between objects with mass
Not all decays are weak-based, though, and not all weak phenomina are directly related to radioactivity. That’s just the only thing a layman has heard of where it’s relevant.
The strong force only holds atoms together through a sort of trickle-down force, too, but that one feels like splitting hairs.
The person I replied to wasn’t able to name the forces beyond gravity, so I think over-simplification and reduction to specific phenomena they would have heard of is appropriate.
Gravity, The weak force, Electromagnetic force, The strong nuclear force
I think there’s a nuclear force, then two others, then another nuclear force. But I could be wrong.
