: Prevents an object from starting its motion. It is equal in magnitude to the applied pulling force until the maximum threshold is reached.

: A force that arises during the relative motion or attempted motion of two contacting bodies and is directed opposite to the direction of motion. fizika 7 klass kirik sila treniia dostatochnyi uroven

: Occurs when one body slides over another. : Prevents an object from starting its motion

(mu) is the dimensionless , which depends on the materials and surface quality. : Occurs when one body slides over another

is pulled along a horizontal floor. The coefficient of friction is

"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
