Seatbelt Safty Newtons Way
First off why do we we wear seatbelts?
We wear seat belats so we wont go flying through the wind sheald when we get in a car accident or when we stop and when we crash, but mostly because it is the law. newtons law is pretty simmalar to that his first law is that when an object is in motion it stays in motion, and when the object isnt in motion it stays in place unless an unexpeceted force pushess it off its corse.
so what dose inertia have to do with any thing?
its the main part its what keeps an object in motion when it moving in one direction and when it is not motion keeps it still the more mass the more inertia and the less mass the less inertia.
