The direction is always perpendicular to the direction of motion, the direction changes momentarily and points to the center of the circle. Regardless of whether the magnitude of the acceleration a changes, the direction of a changes momentarily, so the circular motion must be a variable acceleration motion. It can be understood as the component of the circular motion object acceleration in the direction pointing to the center of the circle.
Centripetal acceleration calculation
Centripetal acceleration: a=v2 / r
r = radius
v = speed
