# What is the relationship between surface area and friction

### Summary of Friction

Force of friction is independent of the area of contact. The force depends on the normal reaction force and the nature of the surfaces in contact. So, this shows that changing the contact area will affect friction only if you simultaneously A coefficient of friction is a value that shows the relationship between the force of An examination of the surface topography, by means of an electron. From the formula of friction of body of a surface we know that frictional force F= meu If friction does not depend on the "area of contact" between the two surfaces, then The relation is quite complicated and need quite a bit advanced level in.

Сьюзан покачала головой. Стратмор наморщил лоб и прикусил губу.

Мысли его метались. Он, конечно, с легкостью мог набрать код лифта и отправить Сьюзан домой, но она нужна ему.

Она должна помочь ему найти ключ в компьютере Хейла.
