Question
The seat belts are provided in the cars so that if the car stops suddenly due to an emergency braking, the persons sitting on the front seats are not thrown forward violently and saved from getting injured. Can you guess the law due to which a person falls in the forward direction on the sudden stopping of the car?
- Newton’s first law of motion
- Newton’s second law of motion
- Newton’s third law of motion
- Newton’s law of gravitation
The correct answer is: Newton’s first law of motion
