Whiplash Injury Explanation:
When a vehicle is hit from behind and the head restraint is not appropriately adjusted, the rapid forward acceleration of the body causes the head to lag behind due to inertia, resulting in a whipping motion. This can lead to a whiplash injury where the tissues in the neck must provide a large force to try to keep up with the body's movement.
- Newton's Third Law comes into play where the tissues in the neck experience an intense acceleration to the opposite direction of the impacting force.
- A whiplash injury is a result of the sudden and forceful movement of the head relative to the body, causing strain on the neck structures.
- Properly adjusted head restraints help reduce the risk of whiplash by supporting the head's movement along with the body, minimizing the strain on the neck tissues.
