I WONDER - What Is Friction?

Friction occurs when two objects rub against each other, opposing motion. The level of friction depends on the materials and roughness of the surfaces involved. A rougher surface produces more friction. For instance, a bowling ball rolls further on a wooden floor than on a carpet due to less friction on the wood.

What causes friction between two objects?

In what direction does friction act in relation to motion?

What factors determine the amount of friction between two surfaces?

How does the roughness of a surface affect friction?

Why does a bowling ball travel further on a wooden floor compared to a carpeted floor?
