SURFACE FRICTION

In an effort to gain a better understanding of the world around us, we have recently begun to use a new technique to investigate the organization and functionality of the diverse parts of our experimental model. We are currently looking to expand this work by collaborating with other labs who have the facilities and prior experience to investigate this project further.

FRICTION

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction described below.

TYPES OF FRICTION

  • Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic friction between moving surfaces. With the exception of atomic or molecular friction, dry friction generally arises from the interaction of surface features, known as asperities

  • Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.

  • Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.

  • Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.

  • Internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation.
