Question

Why does the space station not fall down?

Answer 1

Actually the space station is always falling but never hitting the ground. Due to inertia, a moving object continues moving in a straight line unless a force acts on it. There is a force that acts on every object near Earth, the force of gravity. For ex. if you throw a ball, it does not continue moving indefinitely in a straight line because gravity causes it to move toward the center of the Earth. In a few seconds, the ball collides with Earth and the force of friction stops its motion.

Answer 2

R is the distance from the center of the Earth to the object in orbit. So, the object isfalling towards the Earth, but just keeps missing the Earth. This is the real reason astronauts float inside the International Space Station (ISS) - they, and the vehicle are in free-fall.
