When a car stops suddenly we fall forwards, this is because the upper part of our body tends to continue to be in motion due to inertia. Whereas lower part connected to the car comes to rest with the car. Thus, we fall forwards.

Why does your body go forward when a car stops?
You and the car have inertia. If the car comes to a sudden stop, your body tends to keep moving forward. When the car starts moving again, your body tends to stay at rest. You move forward because the car seat exerts an unbalanced force on your body.
Why does Passengers jerk forward when I brake?
Originally Answered: When the driver applies the brake suddenly, why does the upper part of the passenger jerk or move in a forward direction? An object in motion tends to stay in motion. The passenger has inertia taking them forward. The force of the brakes works on the tires.
Why does this person fall off the back of the truck when the car starts moving?
Since the victim's back is against the seat of the car, the back moves forward with the car. But the head has no direct horizontal force to push it, and so it "lags behind". The victim's body is literally pushed forward, out from under their head - the head is not thrown backwards.
