Upon sensing a collision the seat belts lock in place. When the car breaks, there is no unbalanced force acting on the person, so they continue forward (Newton's First Law). The person moves against the seat belt, exerting a force on it. The seat belt then exerts a force back on the person (Newton's Third Law).
similarities:
1. They both show bilateral symmetry.
2. Both vertebrates and invertebrates have a functional nervous system.
3. Both vertebrates and invertebrates have a heart and a circulatory system.
