Have you seen how wheels move on different surfaces like sand, gravel, grass on or a proper road? What are the differences you see?

Answer:

The difference you can see is due to the (coefficient of) friction between the wheel and the different surfaces mentioned. Wheels moving on rougher surfaces like sand and gravel are slower compared to wheels moving on softer surfaces like grass or on a proper road.

Explanation:

Friction is affected by how smooth a surface is. Assuming that the wheel that is moving on the different surfaces have the same friction, the different surfaces have different values of the coefficient of friction. A proper road is smoother than a grass, which is smoother than sand, which is smoother than gravel.

Because of these differences, friction (force resisting the sliding or in this case, rolling of a solid object over another) also differs. There is more friction when the object/surface that the wheel is rolling in is rough, and less friction when it is smooth.

In this case, the wheel moving in rougher surfaces like gravel and sand tend to be moving more vertically (up and down) because there are empty spaces between the surface/s and is slower because there is more friction while the wheel moving in smoother surfaces like the grass and the proper road tend to be moving less vertically and is faster because there is less friction.
