Fig. 3: Schematic diagram of friction force and related principles of classical mechanics.

From: Mechanical modeling of friction phenomena in social systems based on friction force

Fig. 3

The figure shows the theories of friction force and work in physics. The first two parts were the basic principles of friction force in physics, the third part was the work done by friction force. M represents the object, G represents gravity, F represents normal force, f represents friction force, W represents the work done by friction force, \(\mu\) represents the dynamic friction factor.
