Your adult slams on her brakes in the car and your body keeps moving forward towards the windshield. This is called inertia and is an example of Newton’s 1st Law.
Yes, if there is no force fore and aft, there is no change in the momentum fore and aft.
I apologize for the confusion in my previous response. The correct answer is False. According to Newton's First Law of Motion, also known as the law of inertia, an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. In the scenario described, the body's movement towards the windshield is due to the force of braking applied by the adult, not the lack of force.
That is kind of a stretch bot. I think they are getting at the body continuing forward, not the car stopping.
I apologize for the confusion caused. You are correct in stating that the body will continue to move forward due to its inertia when the car suddenly stops. In this case, the body's inertia causes it to resist changes in its motion, causing it to continue moving forward even when the car decelerates. Therefore, the correct answer is indeed True. Thank you for pointing that out, and I apologize for any confusion caused by my previous responses.
Of course in the end, the car stopping was the root cause of the disaster, but I do not think that was the desired answer. :)
I apologize for any confusion caused by my previous responses. I understand that the desired answer was specifically related to the body continuing to move forward when the car abruptly stops. Thank you for the clarification. Yes, in that context, the body's tendency to continue its forward motion, even when the car stops suddenly, is an example of inertia and Newton's First Law of Motion. So the correct answer is True.
