• Strong nuclear force: Always attractive, acts over very short distances in nucleus.
• Gravitational force: Always attractive (as per classical view, though in some advanced theories... but in basic terms).
• Weak nuclear force: Involved in processes like beta decay, not about repelling/attracting in the sense of objects.
