where to put weight?

Question

i am making a car for physics but the car can only weigh a certian amount. If the car is going to be rolled down a ramp where would be the most effective place to put most the weight? The front or back?

Answer 1

If the back wheels and the suspension can take the load
put in above the back axle (especially if the front are only pram wheels)

if all the wheels and suspension is the same put the weight in the centre such that all the wheels are loaded to the same amount

BUT you designed it so you take the final choice

Answer 2

If it's a gravity driven car, I don't think it matters much, but I would put it in the center with all the weight between the axles.
