Which force pulls inward toward turn center?

Which force pulls inward toward turn center?

• A. Weight shift
• B. Longitudinal transfer
• C. Centripetal force
• D. Sliding friction

Answer: (C)

When a vehicle turns, there must be a force pulling toward the center of the turn to keep it following a curved path. That inward pull is centripetal force—the net inward force required for circular motion. In most driving scenarios, static friction between the tires and the road provides this inward force, allowing the car to stay on the turn. Weight shift describes how weight moves within the car during turning, and longitudinal transfer is front-to-back weight movement during accel or decel, but neither is the inward pull toward the turn center. Sliding friction acts opposite the direction of motion at contact surfaces, not as the inward centripetal pull. So centripetal force is the force pulling inward toward the turn center.
