The potential dangers of loose objects in vehicles are strongly associated with Newton's First Law of Motion, inertia. Inertia is when an object in motion tries to stay in motion, and an object at rest tries to remain at rest, unless the object is acted upon by an outside force. For example, say a car is traveling along a straight road. Loose objects in the auto are "acted upon" by the body, seats, or some …

A split second later, the gas quickly disappears through tiny holes in the bag, thus deflating the bag so the driver or passenger can move.
