What happens when a car suddenly stops?

When a car suddenly stops, the momentum of the vehicle causes it to decelerate rapidly, which can result in a jolt for the occupants. Depending on the speed and the braking force, the car may skid if the brakes are applied too harshly. Additionally, if the vehicle is in motion, any loose objects inside may shift forward due to inertia. In terms of safety, sudden stops can increase the risk of collisions if other vehicles are not able to react in time.
