The equations for circular motion are identical to those of linear motion except for variable names. True False

The equations of angular motion are valid for θ in degrees or radians. True False

Two objects are on a rotating disk Two objects are on a rotating disk. Object A is half the distance from the center of the disk as object B. Which object has a larger angular velocity? Object A Object B They have the same angular velocity at any given time

Two objects are on a rotating disk Two objects are on a rotating disk. Object A is half the distance from the center of the disk as object B. Which object has a larger angular velocity? Object A Object B They both have the same linear velocity at any given time.

Under constant acceleration, linear velocity is related linearly to Angular velocity Radius of rotation Neither A or B Both A and B

Radial acceleration can be written in terms of either angular or linear velocity. Well of course! Of course not, that would be silly.
