Static equilibrium is a form of equilibrium that occurs when an object is at rest. "Static" refers to the object being motionless while "equilibrium" refers to the object either having no net forces acting upon it or having all of its net forces balanced. When forces move an object slightly, and then it stops moving, that is neutral equilibrium. The centre of gravity lies directly at the point of support or suspension. An example of this is rolling a ball slightly so it stops soon after the movement begins.
