Question

1. A rusty bolt is hard to get turned. What could be done to help get the bolt turned? * A. use a long-arm lever B. use a short-arm lever C. decrease the force D. apply the force at a 30 degree angle 2.Which of the following statements show the properties of angular displacement and linear displacement? A. θ, for points on a rotating object depends on their distance from the axis. B. The displacement, for point on a rotating object, does not depends on their distance from the axis of rotation C. θ, for points on a rotating object does not depends on their distance from the axis. D. The displacement, for point on a rotating object, depends on their distance from the axis of rotation.

Definition Definition Angle at which a point rotates around a specific axis or center in a given direction. Angular displacement is a vector quantity and has both magnitude and direction. The angle built by an object from its rest point to endpoint created by rotational motion is known as angular displacement. Angular displacement is denoted by θ, and the S.I. unit of angular displacement is radian or rad.
