In this episode of O Wow Moments featuring Mr. O from the Childrens Museum of Houston, we are exploring the Gears Table. Gears are a simple machine, which means they help you do work, but they cant do work for you. That means there is a trade off -- you can either have more speed or more force, but not both. Whether you get more speed or more force depends on how you arrange your gears.
