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. 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 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 . U. se the points G(2, -4) and H(-6, -6) to answer the following:. 1.. Find the slope of . 2. . Find the midpoint of . 3. . Find GH.  . Warm Up. Objectives. Identify and draw rotations. .. Identify and describe symmetry in geometric figures. 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. ?. 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?. 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?. modest but reliably reproducible and specific group-by-task interaction; color guard speed sensitivity exhibited a rotational motion advantage and radial motion disadvantage. Additionally, rotational and radial speed sensitivity failed to predict each . 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?. HTHS AP Physics 1. M. Dimler. Torque. Torque. is a force that causes an object to turn. Torque. - Force directed perpendicular to the “lever arm” of an object that has the ability to rotate the object around a fulcrum or axis. . Circular Motion and Linear Analogues. Recap. Yesterday, we verified that the circumference of a circle is the distance travelled in one rotation. That means: . We can extend this new knowledge to anything moving in a circle. The distance travelled in one rotation around the axis is equal to the circumference of the path taken….

Rotational Motion – Torque and Angular Momentum AP Physics 1 Torque Forces with equal strength will have different effects on a swinging door. The ability of a force to cause rotation depends 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 .
