If gravity in space is still about 90% as strong as it is on the ground, why do astronauts float around the International Space Station? In this video, we explain in simple words why "zero gravity" is a myth — and how astronauts, their coffee, and the entire ISS are actually in a permanent state of freefall around Earth. Whether you're a curious student, a space enthusiast, or someone who has always wondered how orbits really work, this simple breakdown of microgravity, Newton's cannonball, and orbital speed will finally make it click.
