There are three possible hypotheses:Smaller wheels means car rolls slower.Wheel size makes no difference.Smaller wheels means car rolls faster.Take your pick and then use the data to test your hypothesis.
because the weight of your wheels and the size has wind Resistance on your car
Aerodynamics of the car, the size of the wheels, the weight of the car, and the size of the CO2 cartridge.
A car rolls by using it's wheels.
when you are parking UPhill.supposedly then if the car rolls the wheels will contact the curb and stop the car. Down hill turn to the right
neither
The placement wouldn't affect the speed, but would affect the handling.
To the left, so if the car rolls it will hit the curb and not swing into traffic.
yes
it depends on the year, model, make and whatever size wheels are available.
The more weight over the drive wheels, the more traction.
The variables for a mouse trap car could include factors such as the weight of the vehicle, the size of the wheels, the type of propulsion system used (rubber band, mousetrap spring), and the surface friction of the wheels on the ground. Each of these variables can affect the performance and efficiency of the mouse trap car.
