Torque

Luke Enns English 8 cards

Cards in this deck (8)

1A measure of how much a force acting on an object causes it to changeTorque
2Torque can be used interchangeably with the terms...moment or moment of force (takes the place of force in rotational kinematics)
3How is torque calculated?Torque equals the radius times force sin theta where theta is the angle between the applied force and radius
4What is torque also equal too?Torque=(rotational inertia)(angular acc.)
(rotational inertia takes the place of mass in rotational kinematics)
5In what situations is an object in rotational equilibriumIf the object is stationary or rotating at a constant speed
6How can rotational equilibrium be calculatedNet torque=0
7How do torques add to each otherclockwise torques are negative and counter clockwise torques are positive
8What is angular momentummvr, (takes the place of velocity in rotational kinematics - torque measures the rate of change for angular momentum)
delta(L)=(Torque)(time)
