The diagram shows a vehicle moving forward with a crate on its roof.

Based on (Newton’s first law, Newton’s second law, Newton’s third law), if the driver applies the brakes and the vehicle comes to a sudden stop, the crate will continue moving forward at a constant velocity due to inertia. Based on (Newton’s first law, Newton’s second law, Newton’s third law), when the car stops, the wheels exert a downward force on the ground, and the ground exerts an equal and upward force on the wheels.
