Explain (wit diagram) how uniform circular motion is an example of an accelerated motion?

• Physics -

Acceleration describes the change in velocity which is the vector, therefore, velocity may chage its magnitude and direction. Each case is described by the component of acceleration.
The change in magnitude of velocity is described by tangential component of acceleration
a(tangential) = dv/dt.
The change in direction of velocity is described by normal component of acceleration ((or centripetal acceletarion)
a(normal) = v²/R.
Unoform circular motion : constant magnitude, changing direction => centripetal acceleration
