WHAT IS THE RELATIONSHIP BETWEEN FRICTION AND DIFFERENT SURFACES?

• Some kind of science, not "DHJ" -

Assistance needed.

Two things:

1. Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.

2. When you type in all-caps, two things happen:
**it's the online equivalent to SHOUTING.
Please just type in regular mode, not with the Caps Lock feature turned on. Thanks.

Different pairs of contacting surfaces have difference friction coefficients, and the difference is even greater if they are wet or lubricated. Your question is too vague to tell you more than that. A Google search will provide you with a lot more information.
