Physics - Mechanics - Friction - Static and kinetic friction - Friction Paradox
Present surprising friction facts as true/false questions. (1) 'It takes MORE force to START pushing a heavy box than to KEEP it moving' (True - static > kinetic friction). (2) 'Friction always slows things down' (False - friction helps you walk!). (3) 'Doubling the weight doubles the friction' (Tru
