Until now weve dealt with linear problems with 1 or 2 dimensions. Now its time to consider something moving in a circle and centripetal force. As you will see, angular displacement, velocity, and acceleration differ from their linear counterparts. Fear not, as there are simple conversions you can use to convert from linear to angular components. In addition to angular components you will take a look at reference frames, which are the basis for more advanced physics courses. After you have the math down, its time to look at diagramming another crucial part of physics problem solving.
Once around a circle is 360 degrees, or 2*Pi radians, where a radian is the distance around an arc equal to the length of the arc’s radius.
Angular velocity is the time rate of change of the angular displacement, or the first derivative of the angular displacement with respect to time.
Angular acceleration is the time rate of change of the angular velocity, or the first derivative of the angular velocity with respect to time, or the second derivative of the angular displacement with respect to time.
The direction of the angular velocity and angular acceleration vectors is given by the right hand rule.
There is no way to distinguish between motion at rest and motion at a constant velocity in an inertial reference frame.
