Precession is a motion exhibited by rotating objects which change their angular momentum when subjected to torques, in accordance with Newton’s Second Law, and whether you realize it or not, torques and angular momentum have an impact on your everyday life. If you rode your bike today, the angular momentum of the wheels helped you maintain your balance.. P221: November 8, 2013. Summary. Linear momentum. Angular momentum. Clicker Question. A student is riding on the outside edge of a merry-go-round rotating about a frictionless pivot. She holds a heavy ball at rest in her hand. If she releases the ball, the angular velocity of the merry-go-round will:. Angular momentum of a rigid rotating object. Conservation of angular momentum. Lecture . 23: . Angular momentum.

A . gyroscope. is a device for measuring or maintaining orientation, based on the principles of conservation of angular . momentum.. A mechanical gyroscope is essentially a spinning wheel or disk whose axle is free to take any orientation. This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscope's high rate of spin.. Chapter 11.

Conservation of . angular momentum.  is the principle that the angular momentum of an object remains constant as long as no external . torque,.  or moment, acts on that object. When a figure skater is in the air, he or she is rotating about his or her center of mass and possess a certain amount of angular momentum. The only external force is gravity. However, gravity acts vertically down through the . Rotational Motion – Torque and Angular Momentum AP Physics 1 Torque Forces with equal strength will have different effects on a swinging door.
