Excerpt

A force that arises when one macroscopic body presses against another.

Motivation for Concept

When one macroscopic body encounters another, the bodies cannot simply pass through each other. Instead, their contact results in a change in the motion of each body.

Special Cases

Because contact forces are so common in mechanics, there are several important special cases of contact forces that are commonly encountered.

  • Applied Force:
