Question

Why do astronauts in the International Space Station (ISS) feel weightless even though gravity is still about 90% of Earth's surface value?

Options

• There is no gravity in space

• They are always falling around Earth in orbit

• The ISS is above Earth's gravitational field

• Gravity becomes repulsive at that altitude

Answer 1

They are always falling around Earth in orbit

Explanation:

The source states that in LEO satellites like the ISS, astronauts feel weightless because they are in continuous free fall around Earth, not because gravity is absent.
