The Science of the Circus!

Bello Nock races up a thin wire while riding a motorcycle. He drives the motorcycle high over people's heads. He is a clown with the circus.

Bello's stunt looks scary – and it is. But Bello knows a secret. He knows that he is using science to help keep himself safe. Bello uses the first law of motion in his stunt. This says that a moving object will keep moving until something stops it. Bello uses this law when he rides his motorcycle.

As Bello speeds along on his motorcycle, he sometimes has to stop before slamming into a wall. To stop, Bello uses the motorcycle's brakes. The brakes create friction between the motorcycle tires and the ground. The friction is a force that slows the motorcycle.

The friction changes the movement from the motorcycle into heat energy. You can have fun with friction as heat energy. When you rub your hands together, they should start to feel warm.  This is friction at work!  Friction between your hands changes into heat energy.

Bello always puts on a high-energy show. "I always want to capture the attention of children," he said. He captures their attention with science.
