Description

Present 6 comparisons and ask 'Which has more kinetic energy?' (1) A car at 60 km/h vs a bicycle at 60 km/h (Car - more mass). (2) A car at 30 km/h vs same car at 60 km/h (60 km/h - speed has bigger effect since KE ∝ v²). (3) A bullet vs a bowling ball rolling slowly (Depends on exact values - surpr
