Stable equilibrium

Definition

Stable equilibrium refers to a state where an object remains at rest or returns to its original position after being slightly displaced. In this state, any small disturbance causes a restoring force that brings the object back to its equilibrium position.

Related terms

Unstable equilibrium: A state where even slight displacements cause objects to move away from their original positions.

Neutral equilibrium: A state where objects remain at rest regardless of slight displacements since there is no restoring force acting upon them.

Center of mass: The point within an object where all of its mass can be considered concentrated for purposes of calculating torques.
