TED-Ed: Free falling in outer space - Matt J. Carlson

The video dispels the common misconception that astronauts float in space by explaining that they are actually in a state of free fall, constantly orbiting the Earth. Using Newton's cannonball thought experiment, the video illustrates how orbiting works: objects fall towards Earth but move sideways fast enough to keep missing it. The video also highlights the challenges of achieving orbit, such as the need for high speeds and the risk of burning up due to atmospheric friction.

Explain Isaac Newton's mental experiment involving a cannon and how it relates to orbiting.
