FORT WAYNE, Ind. (Indiana’s NewsCenter) - In this week's episode of Cool Science Monday, Martin Fisher from Science Central teaches us about Gyroscopes and how they relate to tops.

Each have imaginary lines traveling from their top to their bottom, that's where it comes in contact with the ground. The imaginary line is called the axis.

They spin in a circle around that axis. This spinning is called angular momentum. As they spin, friction from the air and ground, and the pull of gravity, causes them to lose energy, slow down, start to wobble (called precession), until they don’t have any more energy to spin. At that point they fall over.
