Question
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
Solution
When a car suddenly brakes, the passenger inside the car continues to move forward due to their inertia. Inertia is the tendency of an object to resist changes in its motion. Since the passenger was initially moving at the same speed as the car, their body wants to keep moving forward even when the car slows down or stops suddenly.
The seat belt worn by the passenger plays a crucial role in this situation. When the brakes are slammed, the seat belt applies a restraining force on the passenger, preventing them from moving forward. However, the seat belt cannot instantly stop the passenger's motion. As a result, the passenger continues to move forward, compressing the seat belt and experiencing a force from it.
It is important to note that the seat belt does not push the passenger forward. Instead, it exerts a force in the opposite direction to the passenger's motion, which helps to slow them down and prevent them from being thrown forward. This force from the seat belt is equal and opposite to the force exerted by the passenger's inertia.
Therefore, the correct answer is that the passenger moves forward against their seat belt because they have the inertia to keep moving forward, and the seat belt provides an equal and opposite force to support their weight and slow them down.

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.
Which of Newton's laws explains why one should always wear a seatbelt?A Newton's first lawB Newton's second lawC Newton's third lawD Newton's fourth law
A car drives along a straight, smooth road at constant speed when it comes to a sudden stop. The occupants are wearing seatbelts. What will happen to the occupants immediately after the car stops? Group of answer choicesThe occupants will accelerate and travel faster than the car was travelling until the seatbelts stop them.The occupants will move up and bump their heads on the roof of the car.The occupants will keep moving with the same speed at which the car was travelling until they are brought to a stop by the seatbelts.The occupants will stop immediately due to the seatbelts.
