Show Me The Physics - Moment of Inertia Race

t = 0.00 s

1× ½× ¼×

Show acceleration

Shapes: Click every shape in the order you think its weight will land, then release.

t = 0.00 s

Every shape: M = 2.0 kg, outer radius R = 15 cm Every string wound on the same light hub, r = 5.0 cm Every hanging weight: m = 1.0 kg, falls 1.50 m

The physics

a = mg / (m + I/r²). Same mass and radius, but where the mass sits changes I. Mass far from the axle means more I, a smaller acceleration, and a later landing.
