Why do we feel weightless in space?
Quick fact
Astronauts are not truly weightless; they are falling around Earth at the same rate as their spacecraft.

Understanding Why do we feel weightless in space?
Weight is a force resulting from gravity acting on mass. In free-fall, both the astronaut and the spacecraft experience acceleration due to gravity.
A deeper explanation
In orbit, objects are in continuous free-fall toward Earth, but they also have sufficient horizontal velocity to maintain their orbital path. This balance creates the sensation of weightlessness.
