Is this a right answer?

Question

Do seatbelts really save lives? Many people have different opinions whether they save lives or take lives. In my opinion, they most definitely save lives more than take them.
The evidence I found is velocity. Velocity includes the speed of an object and the direction of its motion. Most of the time the seatbelts keep you from colliding with objects at high velocity. For example, say you were doing a test run for your vehicle, you drive the car at 30 mph straight into a wall, your body continues forward until it hits the interior of the car. The seatbelt holds you back from going through the window. Also the Forces of the impact in a car accident cause you to go forward.

Answer 1

Basically you have the right idea. Use momentum (mass x velocity) for the motion and the sudden change in speed and/or direction (acceleration) and you get force x time = kinetic energy trying to rip you apart or squash you like a bug.

Answer 2

From the MADD website:

Use of safety belts at the time of a crash makes a significant difference in hospitalization outcomes. One person in six (17%) who was wearing a safety belt at the time of the crash was hospitalized compared to one person in three (32%) who was not wearing a safety belt at the time of the crash. (NHTSA, 2005)


Ejection from a vehicle is one of the most injurious events that can happen to a person in a crash. In fatal crashes in 2004, 74 percent of the passenger vehicle occupants who were totally ejected from the vehicle where killed. Safety belts are effective in preventing total ejections; only one percent of the occupants who used restraints were totally ejected, compared with 29 percent of unrestrained occupants. (NHTSA, 2005)

Answer 3

The proper use of seat belts saves lives. Anyone would have a difficult time coming up with proof that seat belts can cause death.

Answer 4

I DONT USE A SEATBEAT , CAUSE IF THE VEHICLE IS ON FIRE , I AM IN , THE SEATBELT COULD STOP ME FROM GETTING OUT OF THE VEHICLE AND THEN I END UP DYING!
