When an object is turning a corner, the acceleration is directed towards the center of the circular path it is following. This is called centripetal acceleration.

Here's why:

* Velocity is a vector: Velocity has both magnitude (speed) and direction.

* Changing direction means changing velocity: Even if the object maintains a constant speed, changing direction means its velocity vector is changing.

* Acceleration is the rate of change of velocity: Since the velocity is changing, the object is accelerating.

* Centripetal acceleration: The acceleration that causes an object to move in a circular path is always directed towards the center of the circle. This is necessary to constantly change the direction of the object's velocity.
