Need Hypothesis To Test Which Surface Causes The Greatest Friction We Are To Test Which Will Require The Greatest Force To Overcome The Friction Created By A Surface I Need To Write Hypothesis For This Can Anybody Help?

The best thing you can do is research Mechanical Engineering Books. Look Up the Co-Efficient of Friction, it will explain what it is and how to calculate it and how to test materials to find out what it is for that material. I believe rubber has the highest (which is why tyres are made from it) and that the surface area has little to do with it.
