When car takes turn around a curve road, the passengers feel a force acting on them in a direction away from the center of the curve. It is due to__________________?
Correct answer: D. Centrifugal force
- A. Centripetal force
- B. Gravitational force
- C. Their inertia
- D. Centrifugal force
Explanation
Passengers tend to continue moving in a straight line when the car turns, because of their inertia. Relative to the turning car, this produces an apparent outward centrifugal effect. Students often choose centripetal force, but centripetal force acts inward and keeps the car moving along the curve.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
