The is a symbol for change, so basically the
denominator means change in velocity.
We will be bridging together math
(algebra) and science (physics) by
applying the force formula to a vehicle.
Showing the force that the three different
vehicles can exert in kilograms per
square meter.
It has been estimated that the average
crash takes 0.07 seconds, so that is what
we will be using throughout the power
point for the time variable.
Since in the video clips we you will be
viewing the vehicles are traveling at
40mph, or 17.8 meters per second. We
will be using 17.8 m/sec as the velocity
of our vehicles. But since we are using the
change in velocity, which is 17.8 m/sec to
0 m/sec, because the vehicles are
stopping; the change in velocity is -17.8.
Though the negative sign is irrelevant in
this equation.
Time=0.07 seconds
Mass=2,150 kg
Velocity= -17.8m/s*
*Whether or not the velocity is negative or positive is irrelevant.
1. Plug in the numbers for
the variables.
2. Divide 17.8 by 0.07 to
get 254.29.
3. Multiply 254.29 by
2,150 to get 527,373.5
crash test
Time=0.07 seconds
Mass= 730 kg
Velocity= -17.8m/s*
1. Plug in the numbers
for the variables
2. Divide 17.8 by 0.07 to
get 254.29.
3. Multiply 254.29 by
730 to get 185,632.
Time=0.07 seconds
Mass=1,620 kg
Velocity= -17.8m/s*
1. Plug in the numbers for the
variables.
2. Divide 17.8 by 0.07 to get
254.29.
3. Multiply 254.29 by 1,620
