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

"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.
