inertia

Inertia means that an object keeps moving in the same manner that it has been moving.

If a car stops suddenly because of a wreck or something, the person's body tends to keep moving. A seatbelt stops the body from moving.

inertia (so that the passengers don't go through the windscreen if the car stops moving)

inertia, because car stops and passenger will still be moving.
