Which type of equilibrium is pictured?

• stable

• unbalanced

• neutral

Most systems are in which type of equilibrium?

• neutral

• unstable

• stable

A system is in unstable equilibrium if, when displaced, it experiences a net force or torque ___________________.

• at the center of gravity of the system

• in the same direction as the displacement from equilibrium

• in the opposite direction as the displacement from equilibrium

A system is in neutral equilibrium if its equilibrium is independent of displacements from its original position.

• its acceleration is independent of displacements from its original position

• its equilibrium is opposite of displacements from its original position

• its equilibrium is independent of displacements from its original position
