A crash causes a car to come to a complete stop in a fraction of a second. What will happen to the passengers that are not wearing safety belts?Multiple choice question.They will continue to travel at the same velocity that the car was moving until a force stops them.They will stop at the same moment the car stops.Their velocity will not change much because they were sitting in the car not moving around in it.They will accelerate to a velocity greater than what the car was moving at.
Question
A crash causes a car to come to a complete stop in a fraction of a second. What will happen to the passengers that are not wearing safety belts?Multiple choice question.They will continue to travel at the same velocity that the car was moving until a force stops them.They will stop at the same moment the car stops.Their velocity will not change much because they were sitting in the car not moving around in it.They will accelerate to a velocity greater than what the car was moving at.
Solution
The correct answer is: They will continue to travel at the same velocity that the car was moving until a force stops them.
This is due to Newton's first law of motion, also known as the law of inertia. This law states that an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the case of a car crash, if the passengers are not wearing safety belts, they will continue moving at the same speed the car was moving before the crash until something stops them, like the windshield, the seat in front of them, etc. This is why wearing a seat belt is so important; it provides the force that stops you from continuing to move forward in the event of a sudden stop or crash.

Paragraph 2 - Think about it. When you’re driving in a car, you may be going 60 MPH or faster. That car is zipping down the road. Then somebody ahead of you locks up his or her brakes. Your driver doesn’t have time to stop. The car that you are in crashes. Your car was going 60 miles per hour. Now it has suddenly stopped. Your body, however, is still going 60 MPH. What’s going to stop your body? Will it be the windshield or your seat belt? Every time that you get into a car you make that choice. I choose the seat belt.Identify the verbs from the underlined sentences and classify them into Transitive and Intransitive Verbs.
Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because2 marksthe passenger is better able to stop themselves in this mannerthe passenger has an equal and opposite force supporting their weightthe passenger has the inertia to keep moving forwardthe passenger is being pushed by the seats of the car
