This is not a force, but your conservation of momentum. For there to be a force, you must have some acceleration, but what you feel is actually your body attempting to continue moving forward until the force of friction and force normal of your seat belt decelerate you.
The seat belt makes an balance forward force because when the car stops you fall forward and the seat belt makes it so the force in your body stays balanced. So it becomes an balanced forward force.
Force of Inertia
Inertia, which is the tendency of an object to resist changes in its motion. When a car stops suddenly, your body continues to move forward due to its inertia until an external force, such as the seatbelt or airbag, stops it.
momentium sorry 4 bad spelling
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.
It is the force of inertia.
Standing passengers on a bus fall forward when it stops due to inertia. When the bus suddenly stops, the forward momentum of the passengers causes them to continue moving forward until they are stopped by a barrier or regain their balance.
The phenomenon you're describing is explained by Newton's First Law of Motion, often referred to as the law of inertia. This law states that an object in motion will remain in motion unless acted upon by an external force. When the subway train stops suddenly, your body continues to move forward due to its inertia until an external force, like the train or a handhold, stops you.
True ... it's called inertia.
When a bus suddenly stops, the inertia of the passengers causes them to continue moving forward until another force (like friction or a seatbelt) slows them down. This phenomenon is known as inertia, where an object in motion tends to stay in motion unless acted upon by an external force.
It keeps you from moving forward if the car is hit or stops suddenly.
