At the "Sufficient Level," students are expected to move beyond simple definitions to applying formulas and understanding the physical relationships between variables.
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:
Note: For constant speed, the pulling force must equal the friction force. Task : To pull a sled at a constant speed, a force of is applied. Find the coefficient of friction. Solution : 4. Key Takeaways for Kirik's Methodology fizika 7 klass kirik sila treniia dostatochnyi uroven

: Prevents an object from starting its motion. It is equal in magnitude to the applied pulling force until the maximum threshold is reached. At the "Sufficient Level," students are expected to
: 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. Types of Friction in Problems The Kirik methodology
: 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)
