When we measure object undergoing circular motion, one of the issues that arise is that we use dimension that are based linearly
Take for example displacement, which is determined as the separation in a straight line between two point.
But what is the displacement when an object undergoes one revolution?
In a linear sense, it is zero. It is at the same position it left.
Thus when an object travels one revolution, its average velocity is also zero.

There needs to be another way of analysing motion that account for this. This is what this lesson is about.
Watch the following video which introduces the concept of measuring angular displacement and velocity. |
