Which side of the gear will move faster?

The outside of the gear will move faster due to the nature of rotational motion. In a gear, points on the circumference travel a greater distance in the same amount of time compared to points closer to the center. This is because the outside edge of the gear has a larger radius and therefore covers a larger arc as the gear rotates.

When a gear turns, every point along its surface is in motion, but the points near the edge must travel faster to keep up with the distance covered by points at a more central position. This principle is important in various mechanical systems where gears are involved, as it affects how power and motion are transmitted within machines. Understanding this concept is crucial for applications in engineering and mechanics, particularly in designing efficient gearing systems.
