Question

Why do we fall forward whene a moving car stop suddenly?

Answer 1

Answer:

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.

Answer 2

Our body fall forward when a car stops suddenly because our lower body is at rest but due to inertia our upper body still remains in motion.
