- Objects rotating or traveling in a circle have
- variables describing their motion similar to the
- ones describing objects traveling in a straight line.
- The variables are related according to the following
- equations (the scalar case is considered here):
-
-
-
-
-
-
- where s is arc length, q is the central angle, w is angular
- velocity, and a is angular acceleration.
- The equations that govern angular motion are parallel to
- the equations governing linear motion. It is merely necessary
- to use q in place of position, w in place of velocity, and a in
- place of acceleration.
