PPT-Physics 231 Topic: Rotational motion

Key Concepts For each translational motion quantity position velocity acceleration force mass momentum kinetic energy there is a rotational quantity Same equations apply Angular velocity sign and . Terra Alta/East Preston School. Rotational Symmetry. If, when you rotate a shape, it looks exactly the same as it did in its original position, then we say that the shape has . rotational symmetry. .. 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’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.. 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. 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?. alignment . Rotational states. Molecular . alignment is suitable tool to exert strong-field control over molecular properties.. Some of research fields in which molecular alignment plays a key role. High harmonics generation. 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.. behaviour. of the universe, from the very smallest scales of sub-atomic particles to the very largest in cosmology. It applies these laws to the solution of practical problems and to the development of new technologies. . Kinetic Energy. The kinetic energy of the center of mass of an object moving through a linear distance is called translational kinetic energy. . KE = ½ mv. 2. As an object rotates it experiences a type of kinetic energy known as rotational kinetic energy. Learn how to excel in AP Physics with this comprehensive guide.
