The goal of this experiment is to examine the physical nature of the two types of friction (i.e.,

The effects of friction are easily observed in everyday activities and yet the physical mechanisms that govern friction can be complex.

Friction is a force that opposes the motion of an object when it is in contact with a surface. At the microscopic level, it is caused by surface roughness of the materials in contact and intermolecular in...
