Friction in Biomechanics

A comprehensive set of flashcards on the topic of friction in biomechanics, covering types of friction, laws, and concepts related to motion and resistance.

Friction

A force that resists the motion of two surfaces in contact.

Static Friction

The friction force that prevents surfaces from sliding past each other.

Kinetic Friction

The friction force that acts between moving surfaces.

Dry Friction

Friction that occurs between solid surfaces.

Fluid Friction

Friction that occurs when objects move through a fluid (liquid or gas).

Coulomb's Law of Friction

The force of friction is independent of the surface area of contact.

Normal Force

The force perpendicular to the surfaces in contact, affecting the friction.

Coefficient of Friction (u)

A value that represents the relationship between the force of friction and the normal force.

Internal Friction

Friction that occurs within a material, causing dissipation of energy.

Lubricant

A substance used to reduce friction between surfaces in contact.

Capillary Suction

The effect that moisture or liquid has on increasing friction through vacuum formation.

Aspiration

Small surface irregularities that affect the frictional force.

Traction

The grip or friction available between surfaces, essential for movement.

Drag

The resistance force experienced by an object moving through a fluid.

Surface Drag

Friction caused by the interaction of fluid with the surface of an object.

Form Drag

Friction related to the shape of the object moving through a fluid.

Stress-Strain Relationship

The relationship between stress (force per unit area) and strain (deformation) in materials.
