Sliding friction is a force that opposes the motion of two surfaces sliding past each other. It is caused by the irregularities and roughness of the surfaces in contact. When an object is in motion on a surface, the irregularities on the surfaces interlock and create resistance to the motion, resulting in sliding friction.
Use mathematical representations to analyze the proportion and quantity of particles in solution.
