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.

Describe the process of how an object in orbit misses the Earth.

What is the feeling experienced by astronauts while orbiting the Earth?

What speed must one achieve to orbit the Earth, and what are the consequences of reaching that speed?

Why is it not recommended to try to orbit the Earth by running fast enough?
