 * WHY SHOULD WE WEAR SEATBELTS???

The first law:**An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted on by an unbalanced force.
 * example:**If a car is travelling at a certain speed in a certain direction, it will continue to travel at that speed in the same direction unless it is acted upon by an unbalanced force. A person in the car will continue to move forward unless acted upon by a force; for example, the restraining force of a seat belt.


 * The second law:**
 * example:** If you are moving faster the seatbelt has to use more force

example:**When you move forward and hit the seatbelt the seatbelt catchs you and pushes you back.
 * The third law:

Approximately 35,000 people die in motor vehicle crashes each year. About 50 percent (17,000) of these people could be saved if they wore their safety belts.
 * Facts:**

Of every 100 children who die in motor vehicle crashes at least 80 would survive if they were properly secured in an approved child safety seat or safety belts.

4,200 lives could be saved each year if 90% of the U.S. population wore seat belts.

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.

Of the 32,598 passengers killed in 2002 as the result of an automobile crash, almost 60% were not wearing seatbelts. http://www.wtpdmorris.org/Traffic/programs/Click/sbelt.html
 * How seat belts work**

A seat belt is also called a saftey belt. There is 2 ways a seatbelt can work for your safty. The first way is it is made to keep the your body from going threw the windsheild or touching any part of the car. seatbelts consist of a lap belt and a shoulder belt, which are securely attached to the frame of the car in order to keep passengers in their seats. The seatbelt applies most of the stopping force to the rib cage and the pelvis, widening the area of stopping force so the damage is less. The seatbelt itself, made out of webbing, has more give than a windshield or dashboard making the stop not quite so abrupt. http://www.2carpros.com/how_does_it_work/seat_belt.htm Q: If I'm in a serious crash, what difference will a safety belt make?
