True. This is an example of Newton's 1st law of motion, also known as the law of inertia. The tendency of an object to resist changes in its motion is demonstrated in this situation, where your body continues to move forward towards the windshield due to its inertia even after your mom slams on the brakes, trying to bring the car to a stop.
