It acts at a right angle to the object’s motion and causes the object to constantly change direction.
Explanation: a centripetal force points toward the center, perpendicular to the instantaneous velocity, producing a centripetal acceleration (a = v^2/r) that continuously rotates the velocity vector without changing its magnitude, so the speed stays (approximately) constant.
