Explanation:
Detailed explanation-1: -Answer: Newton’s first law of motion.
Detailed explanation-2: -Seat belts When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton’s First Law). The person moves against the seat belt, exerting a force on it. The seat belt then exerts a force back on the person (Newton’s Third Law).
Detailed explanation-3: -You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.
