Linear acceleration, a, is given by

Angular acceleration, a, is given by

A comparison between these two equations leads to the suggestion that we can find rotational (angular) quantities which are mathematically equivalent to the more familiar linear quantities. In these two equations, we have

and time, of course, is the same in both cases.

We can extend the list as follows:

We can now propose new equations by simply substituting rotational quantities for linear quantities. For example

space
