Why do objects float in orbit?

US, WASHINGTON (ORDO NEWS) — If 90 percent of Earth’s gravity reaches a space station, then why do astronauts float or fly there?

The answer is that they are in constant free fall. In a vacuum, gravity causes all objects to fall at the same speed.

The mass of the object does not matter. If a person on Earth drops a hammer and a feather, air friction causes the feather to fall more slowly. But if there were no air, they would fall with the same acceleration.

Some amusement parks have free fall rides in which a ring cabin with passengers descends along a tall tower in the center. If a person let go of an object at the beginning of a fall, then the person and the object would fall with the same acceleration.

Because of this, the object will seem to soar in front of a person. This is exactly what happens on the spaceship.

The spacecraft, its crew and any objects on board it fall to the Earth, rather than flying around it. As they all fall together, the crew and all objects inside the ship seem to be floating relative to the spacecraft.
