I'm a web developer who has lost his touch with Physics 6 years ago and now I'm implementing a certain animation, I just want to know whether I'm calculating it correctly
Given a wheel of radius $r$, rotating at $n$ times per second, how much distance will it cover in $T$ seconds?
The way I solved it -
rotations per second = $n/sec$
$\therefore$ distance covered in 1 sec = $2\pi rn$
$\therefore$ distance covered in $T$ sec = $2\pi rnT$
Did I do this correctly?
