O Wow Moment: What's a Gear to Do?
Channel: Children's Museum Houston
Date: 2011-10-07

In this episode of O Wow Moments featuring Mr. O from Children's Museum Houston, we are exploring the Gears Table. Gears are a simple machine, which means they help you do work, but they can't 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.
