Question

multiple choice question
a wheel rolls over four surfaces. which surface would cause the least amount of rolling friction?
o grass
o concrete
o dirt
o ice

Explanation:

Rolling friction depends on the smoothness of the surface. Ice is the smoothest among the given options. A smoother surface offers less resistance (rolling friction) to the rolling wheel. Grass and dirt are uneven and rough, causing more friction. Concrete is smoother than grass and dirt but not as smooth as ice.

Answer:

ice
