Dr. Matt J. Carlson: Free falling in outer space (2013x352)

:

If you were to orbit the Earth, you'd experience the feeling of free fall, not unlike what your stomach feels before a big dive on a roller coaster. With a little help from Sir Isaac Newton, Matt J. Carlson explains the basic forces acting on an astronaut and why you probably shouldn't try this one at home. [Directed by Josh Harris, narrated by Matt J. Carlson].
