Factors affecting sliding friction

Dong: Feng Xiaoxia, Eighth Grade Instructor of Yulin No.10 Middle School, Shaanxi Province. Admission ticket number: 352322020 1.

Key words: the magnitude of sliding friction is related to the pressure between two objects in contact with each other and the roughness of the contact surface. When the roughness of contact surface is constant, the greater the pressure, the greater the sliding friction; When the pressure is constant, the rougher the contact surface, the greater the sliding friction.
