: Occurs when one body slides over another. is pulled along a horizontal floor

is the . On a flat horizontal surface with no other vertical forces, 2. Types of Friction in Problems The Kirik methodology typically tests three distinct types: fizika 7 klass kirik sila treniia dostatochnyi uroven

"Sufficient level" problems often require 2–3 steps of calculation, such as finding the mass of an object given the friction force and coefficient, or determining the coefficient of friction from experimental data. Task : A wooden crate with a mass of

. What force is required to move the crate at a constant speed? : Calculate gravity force: Calculate friction:
