What is tangential and radial acceleration ?

Variation OF Radial and Tangential Acceleration in Circular motion

Assertion : For uniform circular motion it is necessary the speed of the particle is constant. Reason : There is no tangential force or tangential acceleration acting on particle in uniform circular motion.

In a non uniform circular motion, the acceleration on the particle is

A particle is performing non UCM, the acceleration of the particle is veca_(R)=veca_(r)+veca_(T) , where vec a_(r) is radial component of acceleration. If veca_(r)=0 , the motion of the particle is

The tangential and radial acceleration of a particle are a(t) and a(r) respectively. The motion of a particle is circular if

A particle moves in a circle with constant tangential acceleration starting from rest. At t = 1/2 s radial acceleration has a value 25% of tangential acceleration. The value of tangential acceleration will be correctly represented by
