Explain why a passenger in a car jerks forward when the brakes are suddenly applied. 

When a car is moving forward, both the car and the passengers inside it are traveling at the same speed. When the driver suddenly applies the brakes, the car decelerates rapidly due to the friction between the brakes and the wheels. However, the passengers’ bodies, due to inertia, tend to continue moving forward at the original speed.
