Why do we need seatbelts? Most of us don't question this. This activity visually demonstrates inertia--how your body keeps going after the car has been stopped by a collision. This activity is set up like a lab, but would work just as well as a station. The directions are written directly to the students so you don't have to introduce them. This is a great addition to a study of Newton's laws of motion.
- Objects in motion tend to remain in motion.
- Objects at rest tend to remain at rest.
- Unbalanced or outside forces produce acceleration (a change in motion).
