The acceleration in a circular motion is directed towards the centre and is directly proportional to the radius of circle if it has uniform angular velocity. Is circular motion with uniform angular velocity simple harmonic motion?

No. Simple harmonic motion is the 2-D projection of uniform circular motion on a plane.

1$\begingroup$ +1; Probably, OP is meddling periodic motion with simple harmonic motion. Though every SHM is periodic, every periodic motion is not SHM. $\endgroup$– user36790Commented Dec 23, 2015 at 4:33

$\begingroup$ I don't think the answer is a straightforward no. The two are closely related and you can think about uniform circular motion as a two-dimensional SHO. SHO is one-dimensional, btw. $\endgroup$ Commented Dec 23, 2015 at 10:47
