HOW SEAT BELTS AFFECT DRIVERS DURING A CAR CRASH?
WHY WE SHOULD ALWAYS PUT ON A SEAT BELT WHEN ENTERING IN A CAR?
Seat belts use two main ideas to protect passengers during a car accident. First, they slow the passenger down more slowly than the passenger running into steering wheel or dashboard. This keeps the force required to stop them smaller. It also prevents the person from contacting any of the glass windows in the car or continuing on to be stopped abruptly by the road, tree, or another automobile. The video clip above shows the role of the seat belt during an accident.
Cars are designed with crumple zones so they may slow down over a longer period of time, which keeps the force smaller However, this safety feature alone will usually not prevent serious injury or death to the occupants of a car during an accident. The crumple zone only slows the car more gradually. The only way it slows the occupants more gradually is if they are attached to the car. Otherwise, the car may come to rest more slowly but the people come to rest immediately upon striking the already stopped interior of the car. Stopping in a small amount of time means the force must be very large. This video clip shows some very dramatic scenes of car crash tests with test dummies who are not wearing seat belts. Specifically look for cars crumpling and people stopping in very small amounts of time

WHEN APPLYING NEWTON'S SECOND LAW OF MOTION...
to car accidents and the use of seat belts,
the net external force on apassenger's body
is the mass of the vehicle multiplied by the cars
acceleration. The proper use of a seat belt reduces
the external force of an accident and distributes the
initial inertia of the collision across the body. This is
good to have happen during the crash, because this
reduces the force felt by the driver when he or she is
in a high impact car crash and/or finder bender.

IMPORTANCE OF THE SEAT BELT
SEAT BELTS ARE THE BEST PROTECTION IN A CAR ACCIDENT.
Failure to wear a seat belt contributes to more fatalities than any other single traffic safety-related behavior. 63 percent of people killed are not wearing seat belts. Wearing a seat belt use is still the single most effective thing we can do to save lives and reduce injuries on America's roadways.
Data suggests that education alone is not doing the job with young people, especially males age of 16 to 25 the age group least likely to buckle up. They simply do not believe they will be injured or killed. Yet they are the nation's highest-risk drivers, with more drunk driving, more speeding, and more crashes. Seat belts are the most effective safety devices in vehicles today, estimated to save 9,500 lives each year. Yet only 68 percent of the motor vehicle occupants are buckled. In 1996, more than 60 percent of the occupants killed in fatal crashes were unrestrained.
If 90 percent of Americans buckle up, we will prevent more than 5,500 deaths and 132,000 injuries annually.
The cost of unbuckled drivers and passengers goes beyond those killed and the loss to their families.

THERE ARE A LOT OF DIFFERENT FACTORS THAT COME INTO EFFECT DURING A CAR CRASH
There are tons of things to take into consideration when looking into a car
crash, but we’ll be focusing on momentum, force, inertia, and how the seat belt
affects the passengers of a car crash. All of these factors are considered in
Newton’s laws of motion. Newton’s first law states that an object in motion
stay in motion (everything in the car not that’s not attached to the vehicle.)
unless an equal and opposite force acts on it (This being the seat belt,
slowing the driver down.). A driver of a vehicle has many things against
him/her with this being said they need much more to make sure that they are
safe during a crash and/or an accident. One of the safety measures taken is the
use of the seat belt itself. The task of the seat belt is to stop you with the
car so that your stopping distance is greater than if you had no seat belt.
