The discussion centers on the unbalanced force that causes a passenger's body to move toward the windshield when a car suddenly stops. This phenomenon is explained through Newton's First Law of Motion, which states that an object in motion will remain in motion unless acted upon by an external force. The force acting on the car, which can be attributed to factors such as friction or impact, allows the vehicle to decelerate, while the passenger's body continues to move forward due to inertia, resulting in the forward motion toward the windshield.

That's a reasonable answer.Balsam said:I think that the unbalanced force acts on the car- maybe it's a type of force that I haven't learned about. I'm not sure what that force is called. But, the force acts on the car and the car is able to change its velocity, but the person in the car resists it and their body ends up in the position it would've been in had they kept moving at the same constant velocity as before. That's my guess.
