Document Summary
Angular kinetics focuses on the causes of rotational motion. Recall that is a force is applied directly in the com of the object, then that object will undergo a linear acceleration proportional to, and in the direction of the applied force. But, if that force is applied away from object"s com, that object will undergo the same linear acceleration, but will also rotate about it"s com. The product of an applied force and the perpendicular distance from the axis of the rotation of the object it is applied to its called a moment or moment of a force (n. m) This moment or torque will produce a change in the object"s angular velocity. Newton"s 1st law: law of inertia: an object at rest and a rotating object will continue to rotate with a constant angular velocity unless it experiences a net external moment.
