this is because of the law of inertia
Passengers are thrown forward when a moving vehicle suddenly stops due to inertia. Inertia is the tendency of an object in motion to stay in motion, so when the vehicle stops suddenly, the passengers continue moving forward until they are stopped by the seat belt or another object.
Inertia. the laws of mass dictate that an object in motion tends to continue doing so. Basically imagine that when you are running you are throwing yourself forward and when you stop you are trying to catch yourself.
It is due to inertiaInertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion.
The upper body continues to move even as the feet try to stop the body's forward motion. The upper body moves past the feet and legs, and the person falls over onto his hands or face. When leaving a moving bus, the passenger is still moving at the speed of the bus, and air resistance will not slow him appreciably. The first (only) thing to diminish this velocity is the friction of the soles of his shoes when they come into contact with the ground. Unfortunately, this stops the feet before it can stop the rest of the body, so that the upper body and head are carried in an arc forward, then downward to the ground -- the body is no longer supported by the feet and legs, these being some distance behind.
The ball would continue moving forward due to inertia, since it wants to keep moving at a constant speed. When the truck suddenly stops, the ball will keep moving forward until it hits the front side of the truck or another object in the truck bed.
The passenger jerking forward when a bus suddenly stops can be explained by Newton's First Law of Motion, also known as the law of inertia. This law states that an object in motion tends to stay in motion unless acted upon by an external force, such as the sudden stop of the bus which causes the passenger to continue moving forward.
when the vehicle suddenly start the person move backward and when the vehicle stop the person move forward

No it cannot. Even with forward momentum, it could not be said to have stopped.
Newton 3rd law says for every action of force there is an equal and opposite reaction. When a car stops suddenly the passengers want to move opposite toward the windshield so the seat belts prevent this.
When the vehicle coems to a sudden stop the passenger's forward motion continues until something stops it - either the seat-belt (the fabric of which stretches slightly to absorb the force, and from which the passenger is thrown back against their seat by a 'recoil'), or the windscreen. If it is the windscreen which stops the passenger's forward motion, the impact usually breaks the windscreen (and some of the passenger's bones) and the passenger may continue their forward motion by going through the glass. Otherwise the impact reaction on the passenger may well be enough to snap their neck and kill them.
An orange might roll off your cafeteria tray when you stop suddenly due to inertia, which is the tendency of an object to resist changes in its motion. When you abruptly halt your movement, the orange continues to move forward because it wants to maintain its state of motion. This forward momentum can cause it to roll off the edge of the tray. Additionally, if the tray is tilted or not held steady, it can further increase the likelihood of the orange falling off.
Well one is for the fish/whatever marine life, it actually helps them steer themselves through the water. They also can help the fish to stop suddenly when needed. A few others are also to help them move forward or turning. :)
