I had to graph the following data and find the slope:

Normal Force: Frictional Force:

0 0

2.0 0.6

6.0 1.8

9.0 2.7

10.0 3.0

The slope was 0.30. The question that I am confused on is what does this graph's slope represent?

Coefficient of frcition,

μ = frictional force/normal force.

You have to specify whether it is the kinetic or static coefficient. I.e. whether the force was measured while the object was in motion (kinetic) or the force was required to start the object moving (static).
