As you can see from above, the formulas are very much alike in the linear and angular motions so there is not much to be said. However, remember that when using the angular formulas you are not dealing with distances but angles. The formulas are only analogous but not the same. If you try to put in an arc length or something like that you will get back a nonsense answer because they are not meant to deal with those. This does not mean that a problem cannot be done if you are given tangential quantities or the arc length. Recall that the angle, the angular velocity and angular acceleration are related to the arc length, tangential velocity and tangential acceleration by the radius. ; ; Using these conversions you can work with the above formulae.
