Stable equilibrium -When a body is given a small angular displacement, i.e. it is tilted slightly by some external force and then it returns back to original position due to internal forces. Such equilibrium is called stable equilibrium.

Unstable equilibrium -If a body does not return to its original position from the slightly displaced angular position and moves father away when give a small angular displacement such equilibrium is called an unstable equilibrium.

Neutral equilibrium - The body remains at rest in any position to which it may be displaced, no net force tends to return the body to its original state or to drive it further away from the original position, is called neutral equilibrium.

When a body is in rest, and given angular momentum, the body always comes to rest again. It is neutral equilibrium.
