SAFETY FIRST
The speed of the vehicle is, however, the
more important factor. If, for example, the
speed increases from 25 km/h to 50 km/h,
the kinetic energy increases fourfold!
As the vehicle occupants in our example
are wearing no seat belts, their entire
kinetic energy can only be dispersed
through the crash into the wall, should a
crash occur. The consequences would be
severe or possibly even fatal injuries.

B1H-119
If you are driving at a speed of only
30 km/h to 50 km/h, forces which can
easily exceed 1000 kg are exerted on the
body should an accident occur.
The forces exerted on the body will
increase further at higher speeds, e.g. At
twice the speed the forces increase four-
fold!
Vehicle occupants not wearing their seat
belts are thus not "linked" to their vehi-
cle.
In a frontal crash, these people will con-
tinue to move forward at the same speed
as the vehicle was travelling before the
vehicle crashed!
