Physics - Mechanics - Kinematics - Speed vs velocity - Same Speed, Different Velocity?
Present 6 scenarios and ask 'Are these the same or different?' (1) Two cars going 60 km/h - one North, one South. Same speed? (Yes) Same velocity? (No). (2) A car going around a roundabout at constant 30 km/h. Constant speed? (Yes) Constant velocity? (No - direction changes!). (3) A ball thrown up a
