Answer :
Final answer:
Weightlessness in orbit is caused by free fall under the influence of gravity, creating a feeling of weightlessness despite gravity's presence.
Explanation:
Weightlessness experienced by astronauts in orbit is the result of free fall accelerated by gravity. Even though gravity is present, everything inside the spacecraft falls at the same rate, creating a sensation of weightlessness. This occurs because there is no force other than gravity acting on the objects in the spacecraft.
