If two gears are meshed together, how does the rotation of one gear affect the rotation of the other?

Both gears will rotate in the opposite direction
Both gears will rotate in the same direction
Neither gear will rotate
One gear will rotate faster than the other

The correct answer is: Both gears will rotate in the opposite direction

When two gears are meshed together, the teeth on their gears interlock and one gear drives the other. The rotation of one gear will directly impact the rotation of the other gear since they are connected. If the rotation of one gear is clockwise, the other gear will rotate in the opposite direction, counterclockwise. This is due to the teeth of the gears interlocking and the directionality of the gear's teeth. Option B is incorrect as both gears will not always rotate in the same direction. Option C is also incorrect because the gears will rotate unless they are completely stuck or jammed. Option D is incorrect as the gears will rotate at the same speed since they are connected and share the same rotation.
