Is the relationship between velocity and centripetal force a direct, linear or nonlinear square relationship?

non linear square relationship

Explanation:

formula for centripetal force is given as

a = mv^2/r

here a ic centripetal acceleration, m is mass of body moving in circle of radius r and v is velocity of body. If m, and r are constant we have

a = constant * v^2

a α v^2

hence non linear square relationship
