Frontal
crashes
create
very
strong
forces
for
peo-
ple
riding
in
vehicles.

The
vehicle
crashes
into
the
wall
The
physical
principles
are
simple.
Both
the
vehi-
cle
and
the
passengers
possess
energy
which
var-
ies
with
vehicle
speed
and
body
weight.
Engi-
neers
call
this
energy
“kinetic
energy.”
The
higher
the
speed
of
the
vehicle
and
the
greater
the
vehicle's
weight,
the
more
energy
that
has
to
be
“absorbed”
in
the
crash.
Vehicle
speed
is
the
most
significant
factor.
If
the
speed
doubles
from
15
to
30
mph
(25
to
50
km/h),
the
energy
increases
4
times!
Because
the
passengers
of
this
vehicle
are
not
us-
ing
safety
belts
=>
fig.
225,
they
will
keep
moving
at
the
same
speed
the
vehicle
was
moving
just
before
the
crash,
until
something
stops
them
-
here,
the
wall
>
fig.
226.
The
same
principles
apply
to
people
sitting
ina
vehicle
that
is
involved
in
a
frontal
collision.
Even
at
city
speeds
of
20
to
30
mph
(30
to
50
km/h),
the
forces
acting
on
the
body
can
reach
one
ton
274
(2,000
lbs.
or
1,000
kg)
or
more.
At
greater
speeds,
these
forces
are
even
higher.
People
who
do
not
use
safety
belts
are
also
not
attached
to
their
vehicle.
In
a
frontal
collision
they
will
also
keep
moving
forward
at
the
speed
their
vehicle
was
travelling
just
before
the
crash.
Of
course,
the
laws
of
physics
don't
just
apply
to
frontal
collisions,
they
determine
what
happens
in
all
kinds
of
accidents
and
collisions.
What
happens
to
occupants
not
wearing
aml
inya
In
crashes
unbelted
occupants
cannot
stop
themselves
from
flying
forward
and
being
in-
jured
or
killed.
Always
wear
your
safety
belts!

Fig.

A
rear
passenger
not
wearing
a
safety
belt
will
fly
forward
and
strike
the
driver
Unbelted
occupants
are
not
able
to
resist
the
tre-
mendous
forces
of
impact
by
holding
tight
or
bracing
themselves.
Without
the
benefit
of
safe-
ty
restraint
systems,
the
unrestrained
occupant
will
slam
violently
into
the
steering
wheel,
in-
strument
panel,
windshield,
or
whatever
else
is
in
the
way
>
fig.
227.
This
impact
with
the vehi-
cle
interior
has
all
the
energy
they
had
just
before
the
crash.
