Hmmm. I have a question...(adsbygoogle = window.adsbygoogle || []).push({});

We know that the tangential acceleration (At) is equal to the radius (R) multiplied by angular acceleration (Ar), of which At and Ar are vector components.

At = R Ar

Then I was told that Ar = At/R is not a vector equation. Why is that true?
