Because of their width, they were able to use less force to propel them along the carpet. The large wheels were able to glide over the carpet with little ease, due to the low levels of friction that were acted upon them. Although there was friction, the car was able to deal with is much better than the lego car. Because of how smooth everything was put together the gearing of the record car was very smooth, allowing for a very good efficiency. On the record car the mouse trap was put on the center axle, and as the spring pulled the lever arm the axle would spin, but the mousetrap would spin with it. With everything being able to spin the car could move freely, and
