In uniform circular motion the velocity of the object is changing continuously in direction, the object undergoes uniform acceleration which is not a constant vector. However, for a uniformly accelerated motions, the acceleration of the object should be constant. Hence, it is not an example of uniformly accelerated motion.
Kinematic equations for constant acceleration is not applicable for uniform circular motion. Since, in this case the magnitude of acceleration is constant but its direction is changing.
Therefore, Assertion is incorrect and Reason is correct.
