How does a seat belt save your life in a car accident? regarding momentum?

When you are involved in a car accident, there are usually 3 impacts. Vehicle impact, your impact with the interior, and or organs. It is aseat beltevetable to never have any car accidents. So, by wearing a seat belt, you stop the bodily impact with the interior of the car, and reduce the organs impact with your body.|||a seat belt does not save a life i been i 3 crashes and lived without a seat belt but my friend was in one and died with a seat belt the belt that was made to save her killed by snapping her neck there the window called whip lash they dont save any one

|||ookie, if youre going in a car and it suddenly stops your body will want to keep going forward:a body in motion stays in motion and a body at rest stays at rest unless acted upon by an otherwise unbalanced force. the momentum will want your body to keep going forward, but the momentum will want you to keep going forward causing you to fly through the windshield, but thanks to the seatbelt being there it causes you to stop :) haha hope that made sense its been a bit since ive had to answer a question liek thatt in school.|||Newton's First Law of Motion, aka the Law of Inertia states:


Objects not moving will not move until an outside force acts on it, and All objects maintain their momentum until an outside force acts on it.





Because your body has inertia, if you aren't wearing your seatbelt and the car suddenly stops, you will still have momentum and continue to move forward, potentially hitting something in front of you.|||I'm pretty sure that when someone brakes really quickly/ you thrust forward quickly/ stretch out the seatbelt too much (any of these), your seatbelt doesn't keep on rolling out, it stops to catch you, and then after you move back to a normal seating position or unbuckle and rebuckly, it's not as tight anymore.|||I don't think it does, unless you buckle up TIGHTLY, very, very tightly. I don't usually wear belts myself, only because I seem to find it useless in saving my life in a car accident.|||some cars even have the lock effect in place before initial impact. my car (mercedes) has a tightening mechanism that takes place when i go around road curves at a fast pace. it's a nice feature lemme tell ya!|||it has an auto locking mechanism which will hold you in your seat and keep you from flying through the windshield
