Physics - Mechanics - Rotational Motion - Angular velocity and acceleration - Spin Speed Challenge
Present 6 spinning objects and ask 'Which spins faster?' (1) Clock second hand vs ceiling fan (Ceiling fan - more revolutions per second). (2) Car tire at 60 km/h vs bicycle tire at 60 km/h (Bicycle tire - smaller radius, more rotations per distance). (3) Inner track runner vs outer track runner com
