: A force that arises during the relative motion or attempted motion of two contacting bodies and is directed opposite to the direction of motion.

(mu) is the dimensionless , which depends on the materials and surface quality.

: Prevents an object from starting its motion. It is equal in magnitude to the applied pulling force until the maximum threshold is reached. fizika 7 klass kirik sila treniia dostatochnyi uroven

At the "Sufficient Level," students are expected to move beyond simple definitions to applying formulas and understanding the physical relationships between variables.

: Occurs when a body rolls (e.g., a wheel); it is usually much smaller than sliding friction for the same materials. 3. Example Problems (Sufficient Level) It is equal in magnitude to the applied
