When moving around a circle, the direction of the object keeps changing and this is because of centrepetal acceleration acting towards core of circle along the radiuaswhich helps them rotate around a circle.

Newton's law are applicable on all the bodies even if they are at rest or in accelerated frame of reference. We only take this fact of acceleration in the opposite direction when doing any calculation in such frame.
