Last time I was in school Newton's law of motion was F=MA.
Without getting into a lengthly debate it is common sense to me to realize that a larger vehicle will dissipate the energy of a crash better than a smaller vehicle, with all other factors being equal (air bags, vehicle construction)
If you want to argue that point let's bet a million dollars.....you go crash your 2000 lb Yugo into a tree at 35 mph.....I'll crash my 6000 lb Expedition into the same size tree and see who survives better.........
Just to play devils advocate here... all things being equal .... we are assuming the tree represents an immovable object and therefore the decelearation (A or dv) in the good man's second law above is the same for both the Yugo and the Expedition?
It would mean that the Force (F) would be 3 times greater for the 6000 lb Expedition than the 2000 lb Yugo. This would necessitate the larger car be more able to dissipate the energy of the crash than the smaller in order to be as safe.
Don't get me wrong... I'll take the Expedition over the Yugo in the car vs tree confrontation anyday.... but I think that because of it's weitght the Expedition has to dissipate energy better and not vice versa.
Then again I may have that all wrong... it's late!
