Circular Motion
... It acts at right angles to an object’s circular motion, so the force changes the direction of the object’s velocity. Without centripetal force, the object stops moving in a circular path and leads to a straight path that is tangent to the circle. ...

... In other words, we add a negative v i (i.e. opposite direction) to v f . Note that Δv is pointing down which is toward the center of the circle. This means that the acceleration r will also be directed toward the centre of the circle because it is in the direction of Δv . This is why we refer to it ...
