Has anyone actually done controlled experiments to test all these theories on Pinewood Cars… I mean, other than by the Cub Scouts (too many uncontrolled variables)? By the physics formulae it is simple… all weights accelerate by gravity the same… but more weight carries more momentum down the track (opposing the losses due to friction and drag). But the clunkiest cars slapped together at the last minute, full of Lego drivers and wild fins etc (dreamed up by some 8 year old kids) always seem to win over the most slickly engineered rods created by "supportive" dads. So how come?
