PPT-Rotational Equilibrium and Dynamics

Chapter 8 Magnitude of a Torque What is a torque A quantity that measures the ability of a force to rotate an object around some axis r Example Imagine opening a door around a hinge. 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. .. 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. 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 . 11.1 - Torque. Increased Force = Increased Torque. Increased Radius = Increased Torque. 11.1 - . Torque. Only the tangential component of force causes a torque:. 11-1 Torque. This leads to a more general definition of torque:. 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].. © 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 .

Banwell & McCash. © 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.. 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. . Rotational Equilibrium and Dynamics Chapter 8 Magnitude of a Torque What is a torque? A quantity that measures the ability of a force to rotate an object around some axis. r  Example… Imagine opening a door around a hinge. Practice Problems. Newton’s 2. nd. law involving rotations. Practice Problem #2. A person exerts a force of 45.0 N on the end of a door 84.0 cm wide. What is the magnitude of the torque if the force is exerted:.
