PPT-Lab 9: Rotational Motion III: The Gyroscope

University of Michigan Physics Department Mechanics and Sound Intro Labs Gyroscopic Motion Precession is a motion exhibited by rotating objects which change their angular momentum when subjected to torques in accordance with Newtons 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.

WHAT IS A GYROSCOPE?. DEFINITION:. 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.. 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 rotate?. If you ride near the outside of a merry-go-round, do you go faster or slower than if you ride near the middle?. It depends on whether “faster” means . a faster . linear speed (= speed). , ie more . Infrared (Vibrational). Raman (Rotational & Vibrational) . Texts. “Physical Chemistry”, 6th edition, .
