We consider the rotation of . rigid bodies. . A rigid body is an extended object (as opposed to a point object) in which the mass is distributed spatially.. Where should a force be applied to make it . - Class. . 20. Today:. Gravitational Torque. Rotational Kinetic Energy. Rolling without Slipping. Equilibrium with Rotation. Rotation Vectors. Angular Momentum. Pre-class reading quiz on Chapter 12. 11.1 - Torque. Increased Force = Increased Torque. Increased Radius = Increased Torque. 11.1 - . Torque. Only the tangential component of force causes a torque:. 11-1 Torque. This leads to a more general definition of torque:. and rotational inertia. We consider the rotation of . rigid bodies. . A rigid body is an extended object in which the mass is distributed spatially.. Where should a force be applied to make it rotate (spin)? The same force applied at . and rotational inertia.

Dynamics of Rotational Motion. (Conservation of angular momentum). Goals for Chapter 10. Torque: “angular force”. To see how torques cause rotational dynamics (just as linear forces cause linear accelerations). HTHS AP Physics 1. M. Dimler. Torque. Torque. is a force that causes an object to turn. Torque. - Force directed perpendicular to the “lever arm” of an object that has the ability to rotate the object around a fulcrum or axis. . Rotational Motion – Torque and Angular Momentum AP Physics 1 Torque Forces with equal strength will have different effects on a swinging door. The ability of a force to cause rotation depends Chapter 8. Magnitude of a Torque. What is a torque?. A quantity that measures the ability of a force to rotate an object around some axis.. r. .
