and then a second rotation about the yaxis yy. CHE 6416. Michael Evans. 1. How does Microwave relate to other spectroscopies. Different types of motion. Translational. Vibrational. Rotational.. 2. What is Microwave Spectroscopy?. Microwave stimulates Rotational translations. 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 . 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. 10.1 – Angular Position (. θ. ). In linear (or translational) kinematics we looked at the position of an object (. Δx. , . Δy. , . Δd. …). We started at a reference point position (x. i. ) and our definition of position relied on how far away from that position we are.. 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.. Conservation of rotational momentum. 1. Why does a wheel keep spinning. ?. Spinning ice skater . Video. . Why is a bicycle stable when it is moving, but falls over when it stops. ?. Why is it difficult to change the orientation of the axis of a spinning wheel?. © 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. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Simple Harmonic Motion. This week you move away from rotational motion and begin to study simple harmonic motion. We say that you move away from rotational motion only in the sense that you will not be studying rotating objects as the main focus of the lab. However, it is worth noting that several concepts from rotational motion can be related to simple harmonic motion. You will study three simple harmonic oscillators today: the mass and spring system, the simple pendulum, and the ball and dish oscillator.. 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 . 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 . Dedra. Demaree, . Georgetown University. © 2014 Pearson Education, Inc.. Rotational Motion. How can a star rotate 1000 times faster than a merry-go-round?. Why is it more difficult to balance on a stopped bike than on a moving bike?. © 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.. Angular Motion.  .  .  .  .  .  . 1.  .  .  .  .  .  .  .  .
