I understand that circular motion is defined by 2 components of acceleration, one tangential and one radial and their resultant is what causes circular motion.
I am confused though as to why it is said that in uniform circular motion (constant angular velocity) there is no tangential acceleration. How can the radial vector be always pointing towards the centre? Is there is no tangential vector component to it?
So is there still a vectorial tangential acceleration (since the vector points to a different point at each time)?
And is centripetal acceleration the resultant of the tangential and radial accelerations?
