( Hello, my first question ... )
Assume two cars, each with exactly the same body, but one a scaled down version of the other (hence, aerodynamics approach equality):
"junior car" - has an engine that delivers 200 ft-lbs of torque and weighs 3000 pounds
"base car" - has an engine that delivers 400 ft-lbs of torque and weighs 6000 pounds
My question is this: isn't the effect of "mass" non-linear? Doesn't the junior engine have less than half the work to do to accelerate than the base car because momentum, friction, drive train length, drive train mass, turbo charger mass, gearing all drain power in a non-linear way; the larger a vehicle you make? I've done the G-search thing and haven't found any answer to this type of "real world" condition.
(Or, asking the same thing in a different way: would the two vehicles above accelerate with identical track times?)
Thanks for responding.
