hõõrdumistakistus
Hõõrdumistakistus, often translated as friction or resistance to sliding, is a force that opposes the relative motion or tendency of motion between two surfaces in contact. This force arises from the microscopic irregularities of the surfaces and the molecular attractions between them. When two objects are in contact, their surfaces are not perfectly smooth. Even seemingly smooth surfaces have peaks and valleys at the microscopic level, which interlock to resist movement. Additionally, attractive forces between the molecules of the two surfaces contribute to the overall friction.
The magnitude of the friction force depends on several factors. Primarily, it is proportional to the normal
Friction is a ubiquitous phenomenon with both beneficial and detrimental effects. It is essential for many
