Can someone help clarify the difference? Tbr says if you assume you're moving uniformly around the circle, then angular acceleration is zero and the velocity vector always has the same length. (chap 2 of tbr physics ) How can we assume angular acceleration is zero when the velocity vector is changing directions each instant?
They use this logic to then introduce centripital acceleration but since I don't understand this last point I'm getting confused on how the two concepts are related.
Thank you
