The development of other sciences depends in many respects If ,which of the following ratios is the largest? Mathematical Representations of Motion . Unit: Simple harmonic motion and rotational motion. True. All of these equations are on the AP Physics 1 Equation Sheet except the last one. All. Similarly, in rotational equations, moment of inertia resists torque and causes lower angular accelerations. In rotational kinematics equations, what quantity is analogous to force in linear kinematics equations? 10. Colleges agree that Units 8-10 can be removed from AP Physics 1 since they are covered in AP Physics 2; accordingly, Units 8-10 are no longer tested in AP Physics 1. Maximize torque by using an angle of 90 because o Dimensions for Torque are Newtons meters, The greater the inertia on an object, the harder it is to change its velocity. 7.4 Conservation of Angular Momentum.

AP Physics 1 Section. \tau =r\times F=rFsin { \theta } = r F = rF sin Torque is the cross product of two vectors, which means that torque is also a vector. position x displacement v velocity a T tangential acceleration Vectors in rotational motion Use the right hand rule to determine direction of the Physics C Rotational Motion Name:__ANSWER KEY_ AP Review Packet Base your answers to questions 4 and 5 on the following situation. Displays the linear and rotational counterparts for certain concepts. Just as force causes linear acceleration, torque causes angular acceleration. This can be seen most in the linear-rotational comparison of Newton's second law: A boot is put in a stick which is attached to a rotor. The rotor turns with an angular velocity of . What is the linear velocity of the boot? Presentation Created by Martin Kirby. 1704days since AP Physics 1 Exam The magnitude of torque about a axis of rotation is defined to be =rFsin The magnitude of torque about a axis of rotation is defined to be =rFsin. The direction of torque is (given by right hand screw rule). This would cause the angular acceleration to be zero just like translational equilibrium causes the acceleration Rotational kinematics and dynamics, including angular displacement, velocity and acceleration; torque; moment of inertia, and angular momentum Jump to content AP Physics 1/2
