Tactic 1: Units for Angular Variables

We began the use of radian measure for all angular variables whenever we are using equations that contain both angular and linear variables. Thus, we must express angular displacements in radians, angular velocities in rads and rad/min, and angular accelerations ,  are marked to emphasize this. The only exceptions to this rule are equations that involve only angular variables, such as the angular equations listed. Here you are free to use any unit you wish for the angular variables; that is, you may use radians, degrees, or revolutions, as long as you use them consistently.
