How is speed determined in the absence of skid marks?
That is one question I have never ask the Investigators, however....
I am trained in science, Math, And Electronics.
From physics I know that if you take a metal something and apply force to it it will bend now if it is "A little force" (relative to design lmits) it will spring back.. If it's a LOT OF FORCE it remains bent.
If you know the metal, and how badly bent, you can calculate the force.
Einstein said E=MC^2
Lots of folks seem to think that is hard to understand but..
for this we need only make one change E=MV^2
Energy is the product of the mass of the vehicle times the square of the speed. (Velocity).
So having seen many crash test dummy crashes where the speed and other factors were known to a very serious number of decimal points the investigator only needs to compare the degree of damage.
