μdimensionless quantity

KEY CONNECTIONS

Formulas

μ = Ftr / N

Ftr = μN

Ftr = μmg

Ftr = μmg cos α

NOTATION

: Friction coefficient is a characteristic of the resistance to movement of contacting surfaces.
: Friction force is a force that prevents the relative movement of surfaces.
: The support reaction force (normal pressure force) is the force with which the support acts on the body perpendicular to the surface.
: Mass is a scalar physical quantity that is a measure of the inertia of a body.
: Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
: Angle is a quantity characterizing the mutual rotation of directions.
