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.

Angular displacement, angular velocity, angular acceleration. Rotational energy. Moment of Inertia. Torque. Chapter 10:Rotation of a rigid object about a fixed axis. Reading assignment:. Chapter 10.1 to10.4, 10.5 (know concept of moment of inertia, don’t worry about integral calculation), 10.6 to . We’ve seen that the translational motion of a complicated object can be accounted for by the motion of the center of mass. Now, we turn to all the other motions with respect to coordinate system moving with the center of mass. measure device rotation rate. Disclaimer: This document is provided “as-is”.

The results from our plaid stimuli extend those from prior random-dot studies that also showed distinctions . between . these MST-mediated (. radial versus rotational) motion judgments [4-9]. . Future experiments are needed to determine whether the present task effects reflect local speed differences, which can influence radial and rotational speed judgments [10-13].. Physics 1, NTC. Angular Motion, General Notes. When a rigid object rotates about a fixed axis in a given time interval, every portion on the object rotates through the same angle in a given time interval and has the same angular speed and the same angular acceleration.. © 2015 Pearson Education, Inc.. This lecture will help you understand:. Circular Motion . Rotational Inertia. Torque. Center of Mass and Center of Gravity. Centripetal Force. Centrifugal Force. Rotating Reference Frames. 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 .

Why is it more difficult to balance on a stopped bike than on a moving bike?. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Inclined Plane Experiment. Although it may seem daunting, rotational motion is fairly straightforward. In many ways it is analogous to the linear motion that you have studied previously. Rotational motion can be examined using the same principles of energy and momentum conservation that you have used previously. The equations that accompany these laws take a slightly different form, but at their root, they are based on the same physical principles. So begins your three part study of rotational motion which includes this lab, the rotating bar in . © 2016 Pearson Education, Inc.. Goals for Chapter 9 . To study angular velocity and angular acceleration.. To examine rotation with constant angular acceleration.. To understand the relationship between linear and angular quantities.. Key Concepts. For each translational motion quantity (position, velocity, acceleration, force, mass, momentum, . kinetic energy). there is a rotational quantity. Same equations apply. .
