How it works
On a horizontal surface the normal force is N = mg. Static friction can reach up to μₛN and exactly balances a horizontal applied force until that force exceeds the limit; then the block accelerates and kinetic friction with magnitude μₖN opposes the sliding direction.
Key equations
|f_s| ≤ μₛN, |f_k| = μₖN
Sliding: a = (F_app − f_k) / m
