Hello everyone, I've been studying centripetal and centrifugal acceleration and derivation of their magnitude. I noticed in one of Walter Lewin's lectures that the velocity is written as both a vector and an arc length which is confusing to me. When velocity is written as a vector, it has a length that is contained in a line tangent to the circle, where velocity is written as arc length it is the length of the arc traced out by the position vector divided by time. I am wondering if these to scalar quantities are the same, and if so how to prove it.
Looking forward to your feedback, thank you!
