Centripetal force is what keeps the object moving. Centripetal force acts on an object moving in a circular path and the force is directed towards the center of the circular path.
The primary force that helps a car maintain its curve while turning is friction between the tires and the road, which provides the necessary centripetal force. This force stops the car from sliding off and allows it to follow the curved path. Additionally, banked curves can reduce the reliance on friction by using the normal force.
