Explanation:

Physics Concept: Seat Belt and Newton's First Law

When a car suddenly stops, the passengers tend to continue moving forward due to inertia, according to Newton's first law. Seat belts are essential as they exert a force on passengers, bringing them to a halt along with the car, thus preventing injuries.

For example, if a car traveling at 120 km/h suddenly stops, the passengers would also be moving at 120 km/h until the seat belt exerts a force to stop them from moving forward, as explained by Newton's laws of motion.
