Rotational Dynamics Terms and Formulae Terms Torque - The rotational analogue to force. Moment of Inertia - The property of an object that dictates its angular acceleration. Rolling Without Slipping - The special case of combined rotational and translational motion in which the part of the object in contact with the ground has zero velocity. Formulae Definition of torque τ = Fr sin θ Vector definition of torque τ = r × F Relation between τ and α τ = mr 2 α Rotational Analogue to Newton's Second Law τ = Definition of work in angular motion
