Question

A smooth surface exerts more force of friction than a rough surface. True or false ​

Answer 1

Answer:

False

Explanation:

There is more friction between two coarse materials rubbing against each other than between a coarse and a smooth surface. Equally, there is relatively little friction exerted between two smooth surfaces. Sometimes, the frictional force is so great that it prevents movement.

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy

Answer 2

Answer:

the answer is false

Explanation:

Smooth surface exerts less friction than rough surface .
