If an object moves around a circle of radius r at constant speed v, it has an acceleration towards the center of the circle, of magnitude: a=(v^2)/r.

If an object moves around a circle of radius r at constant speed v, it has an acceleration towards the center of the circle, of magnitude:
$a=\frac{{v}^{2}}{r}$

Explanation:
a is directly proportional to v as it can be seen that as v increases awill also increase.
a is directly proportional to r as it can be seen that as r incresinc awill decrease.
