True/False: A smooth plastic wheel generally produces more friction than a rubber wheel.

Explanation:
The main idea here is traction depends on how well the wheel material interacts with the surface at the contact patch. Rubber’s elasticity and micro-texture let it deform slightly and “stick” to the surface, producing a higher coefficient of friction and better grip. A smooth plastic wheel is harder and doesn’t conform to surface roughness, so it tends to slide more easily and offers less friction against the surface. So, a smooth plastic wheel generally does not produce more friction than a rubber wheel; rubber provides greater traction, making the statement false.
