Non uniform circular motion acceleration

[ahmed emad]

In uniform curved motion , I can get the acceleration from the equation :
A = v²/r , but in non uniform the velocity is changing , so will the certipetal acceleration also change ?

Google the Frenet equations. Those equations treat the more general case.

And for an application of the Frenet equations in two dimensions, where the equations are somewhat simpler, see https://www.physicsforums.com/insights/frenet-equations-2-d-result-cornu-spiral/

It's far from my question. I meant will the centripetal acceleration increase?

If the object stays on the same circle of radius $r$, the answer is yes.

Okay , thanks very much.
