Baumgartner's Super Sonic Dive

The video discusses Felix Baumgartner's jump from 37 kilometers above Earth, breaking several records including the sound barrier. It clarifies that this height is not the edge of space, which is politically defined at 100 kilometers. The video explains why not all skydivers break the sound barrier, due to differences in air density affecting terminal velocity. It also covers the limitations of jumping higher due to safety and technical constraints. The concept of gravity and weightlessness is explored, emphasizing that astronauts experience weightlessness due to orbit, not absence of gravity. Lastly, it briefly touches on the psychology of thrill seeking.

What is the politically defined boundary of space?

• 200 kilometers

• 150 kilometers

• 100 kilometers

• 50 kilometers

Why do skydivers not typically break the sound barrier?

• They jump from too low an altitude

• They use parachutes

• They are not fast enough

• They encounter too many air molecules

What factor primarily determines terminal velocity?

• Weight of the skydiver

• Number of air molecules encountered

• Height of the jump

• Speed of the wind

Why didn't Baumgartner jump from a higher altitude?

• The helium balloon couldn't go higher

• He wanted to avoid breaking more records

• He was afraid of heights

• He didn't have a spacesuit

Why do astronauts experience weightlessness?

• They are in a vacuum

• They are outside Earth's gravity

• They are in orbit

• They are too far from Earth
