NOTATION
Quantities in formulas
- \mu
- Friction coefficient is a characteristic of the resistance to movement of contacting surfaces.
- F_{\text{тр}}
- Friction force is a force that prevents the relative movement of surfaces.
- N
- The support reaction force (normal pressure force) is the force with which the support acts on the body perpendicular to the surface.
- m
- Mass is a scalar physical quantity that is a measure of the inertia of a body.
- g
- Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
- \alpha
- Angle is a quantity characterizing the mutual rotation of directions.
