Rotational Motion Rotational Inertia:  That property of an object to resist any change in its state of rotation. If at rest the body tends  to remain at rest; if rotating, it tends to remain rotating and will continue to do so unless acted upon by a net external  torque. Torque:  The product of force and lever-arm distance, which tends to produce rotation. Center of Mass:  The average position of mass or the single point associated with an object where all its mass can  be considered to be concentrated. Center of Gravity:  The average position of weight or the single point associated with an object where the force of  gravity can be considered to ace. Usually the same place as the center of mass. Equilibrium:  The state of an object when not acted upon by a net force or net torque. An object in equilibrium may  be at rest or moving at uniform velocity; that is, not accelerating . Centripetal Force:  A center-seeking force that causes an object to follow a circular path F = (mv`2)/r Centrifugal Force:  An outward force that is due to rotation. In an inertial frame of reference, it is fictitious in the
