Question

Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries.

Answer 1

One example could be because of the law of inertia. 

The law of inertia states that when an object is at rest, it will remain at rest and an object in motion will remain in motion with the same speed and direction unless acted upon by an unbalanced force.

In the case of car crashes, the force and impact can determine the injury you will get.
