Astronauts on the International Space Station appear "weightless." What is the actual reason?
AGravity does not reach the ISS.
BThe ISS is beyond Earth's gravitational field.
CThe ISS and astronauts are in continuous free fall around Earth.
DThe Earth is too small to attract the ISS.
Explanation
📌 The ISS orbits at ~400 km altitude, where gravity is still ~89% of surface value. Astronauts feel "weightless" because they and the ISS fall together — this is free fall, not the absence of gravity. Distractor A: false; B: same as A; D: nonsensical.
