FORT WAYNE, Ind. (www.incnow.tv) -- In this week's episode of Cool Science Monday, Martin Fisher from Science Central will talk about angular momentum.

Martin had his volunteer, 6.5-year-old Noah, explain that angular momentum is when things spin in a circle. Angular momentum is circular motion.

Martin had a large wheel called a gyro wheel. When he would spin it w/ his hand, it was a gyroscope (a top), and had angular momentum (spinning motion). When Noah stood on a lazy susan platform, without changing the position of the wheel in his hand, nothing happened with the platform.

However, when he shifted the position of the spinning wheel in his hands, the change in direction of energy and motion caused the platform to spin.
