L14, ch 10 1 Lect 14 Torque, Angular Acceleration, Rotation about Moving Axis (Sections 10.1-10.4) Application of basic principles to rotational motion: New- ton’s laws apply but their application is facilitated by the use of the concept of torque . ¥ Key Concepts The torque of a force describes the tendency of the force to cause or change rotational motion of the body on which the force acts. The sum of the torques acting on a rigid body is propor- tional to its angular acceleration ; the proportionality constant is the moment of inertia . The motion of a rigid body can always be described as a combination of translational motion of the center of mass and rotational motion about an axis through the center of mass. When a force acts on a rotating body, the work done during an angular displacement is the product of torque and angular displacement . Power is the product of torque and angular velocity.
