Description

A 5-step lesson. Step 1: 'Static friction prevents an object from starting to move. It adjusts to match the applied force, up to a maximum: f_s ≤ μ_s × N'. Step 2: 'Kinetic friction acts on an object already in motion. It's constant: f_k = μ_k × N'. Always less than maximum static friction (μ_k < μ_
