What is the primary physical reason astronauts experience weightlessness in Low Earth Orbit?
Answer
They are falling around the Earth continuously due to incredible sideways speed
Astronauts are not floating because gravity is absent; they are constantly falling towards Earth but moving sideways fast enough (around 17,500 mph) to perpetually miss it, remaining in orbit.
