Question

One radian is defined as the angle subtended by an arc whose length is equal to the radius. True False Angular velocity is defined as change in distance divided by elapsed time change in angular displacement divided by elapsed time change in velocity divided by elapsed time I do not know Angular acceleration is defined as change in speed divided by elapsed time change in acceleration by elapsed time change in angular velocity divided by elapsed time i really don't know this one either The product of the force exerted on a lever is called the moment of the force. It's more common name is torque acceleration pain in the neck tension The distance from the axis of rotation to the line along which the force acts is call the level arm. True False The sum of the torques is equal to the rotational inertia times the rotational acceleration. True False
