Gears Simulation

SMALL GEAR → BIG GEAR

The blue gear pushes the orange gear. Twice as many orange teeth means half the speed. Watch the white dots.

White dots mark the starting teeth.

Blue = driver (motor). Orange = driven (output). Teal = idler (middle gear). Drag to pan; tap any gear to inspect it.

Turning force & energy (optional)

Torque means turning effort, like twisting a handle. Efficiency is the fraction of power passed on; the rest becomes heat.
