Seat Belt
60
The car carrying the passengers who does not fasten his seat belt is driving
towards the wall body.
The car has crashed into the wall body.
Make a brief explanation on the principles of physics in a frontal
collision accident: As long as the car is in motion, the car
including its passengers will have “kinetic energy”. The
magnitude of “kinetic energy” entirely depends on car speed, car
mass and the passengers. Assuming that you accelerate and
increase the car mass, more energy must be offset in the event of a
traffic accident.
The speed of the car is a more important factor. For example, if
the car speed is increased to 50 km/h from 25 km/h, the kinetic
energy will increase by four times! Since the passengers does not
fasten a seat belt in the example, the kinetic energy of the
passengers can be completely offset only by the wall body
collided in the event of a collision accident. The result will lead to
serious injuries and even a danger of life.
Even if you are driving at a speed between 30 km/h, the force
acting on your body can exceed 10,000 Newtons in a crash. It is
equivalent to 1-ton gravity (1,000 kg) . The force acting on the
physical body is even higher when the car is driving at a higher
speed. In other words, if the car speed is increased by twice, the
impact force will be quadrupled!
The passengers without seat belt fastened also means that he has
not been “integrated” with the car. In the event of a frontal
collision accident, these passengers continue to move forward at
the speed prior to collision!
What Happens to the Passengers who does not fasten his seat
belt?
The passengers without seat belt fastened is betting his life in the
event of traffic accident!
