Two meshed gears turn in what directions relative to each other?

Two directly MESHED (interlocking) gears turn in OPPOSITE directions — if one turns clockwise, the other turns counterclockwise. ASVAB Mechanical Comprehension tests gear systems. GEAR DIRECTION: adjacent meshed gears always rotate oppositely. GEAR RATIO/SPEED: a smaller gear driving a larger gear turns the larger one SLOWER but with more torque; a larger gear driving a smaller one turns it FASTER with less torque. To make two gears turn the SAME direction, you add a third (idler) gear between them. Gear direction and speed relationships are commonly tested.
