Frictional Vibrations

Friction is the resistance of a body against movement on a base. Self-excited friction oscillations, also known as slipstick phenomenon, occur if the static friction is significantly higher than the dynamic friction. Static friction means that a body remains at rest under the action of a force. If a limit value is exceeded, the body begins to move on the base, resulting in dynamic friction.

Learning Objectives And Experiments:
Observation of the transition from static to dynamic friction
