Equilibrium pointBroader topic: It applies force and torque balance to mechanical systems.
Normal forceRelated: For a resting object, force balance can determine the normal force's magnitude.
Static equilibriumNarrower topic: Static equilibrium is its zero-velocity case for a body.
Levitation (physics)Related: Static levitation requires weight and supporting forces to balance.
