the smaller the wheel the lesser the weight, the mousetrap car would go faster,
because the wheel make the mousetrap go forward but without the wheels the mousetrap stays in one place
you want to place your mousetrap as far away from the back wheels as possible
Larger wheels have a larger diameter. Therefor, they will cover a greater distance per rotation of the driven axle, compared to a smaller wheel.
the best wheels for your mousetrap car are CD's because when your car takes off the wheels will spin and send your car into a foward rolling motion also the CD's are light soo it will help you win your science award:)
By transferring the spring energy to the drive wheels.
duct tape, mousetrap, wheels ( anything), pliers, end hooks, pop bottle ends,
The more weight over the drive wheels, the more traction.
Use Cd's as wheels to make less friction
u tell me
Because the axle is moving just as many rotations but since the wheels are bigger it's moving a greater distance. Because it's a big wheel, after all the string is gone, the wheels keep moving, which lets your car coast a longer distance.
It is depended on the shape of the wheels to determine how much friction is applied.
