Equilibrium
Also known as: balanced forces
A state in which all forces acting on an object balance so that the net force equals zero and there is no acceleration. Key to analyzing structures, bridges, and stationary objects.
💡 Intuition
All forces cancel out — the object doesn't accelerate, though it may still be moving at constant velocity.
Core Idea
Equilibrium means zero acceleration, not necessarily zero motion.
