Which law would be modeled by the image on the left?
Illustration of a person sitting in an ejector seat. In the first image the upward push of the chair and downward pull of gravity are equal, and the person is at rest. In the second image the upward push of the chair is greater than the downward pull of gravity, and the person accelerates upward?

I apologize for the mistake. The correct law that would be modeled by the image on the left is Newton's First Law. Rest is the natural state of an object, as depicted in the first image where the person is at rest when the upward push of the chair and the downward pull of gravity are equal.
Carla demonstrates Newton’s First Law of Motion by slowly pushing a book across a table. The book moves at a constant rate of speed so long as she is pushing it. Which of the following is NOT true?(1 point)
