| Apr 26, 2021 at 16:05 | comment | added | agavemelon | @DescheleSchilder My question was mainly about notation, to speak. This is what I understood from the answers: we start from $v_t = \omega r$, where all the values are scalars ($v$ and $\omega$ represent speeds). I wanted to know what the time derivative of $\omega$ was called; I cannot call it angular acceleration, because that word already represents the time derivative of angular velocity. We are looking for a name for the time derivative of angular speed. Turns out, this value doesn't have its own standard name, but can be represented as $\hat\omega \cdot \boldsymbol \alpha$ | |

The tangential acceleration of a particle is the acceleration for r is constant. If the particle is accelerated only tangential (r constant, circular motion), then it obviously gains tangential speed. Because of this, the centripetal force is increased. So there is a change in force directed towards the center. Not a change in distance. Is it the change in centripetal acceleration you are interested in? | |

| Apr 25, 2021 at 11:57 | comment | added | agavemelon | @Deschele Schilder I precisely stated in my question that tangential acceleration is the one that I don’t have any problems with, but it’s with angular acceleration. It’s fine though, I have arrived at the conclusion that the value I’m asking doesn’t have its own standard name. | |
