satellite continue to revolve around the planet without falling on it.why?
Answers
Man-made satellites don't fall out of space for the same reason that the moon (a big satellite) doesn't crash into the earth, or that the Earth doesn't crash into the Sun. The reason is actually described through Newton's laws of motion.
A moving object will continue to move in a straight line at the same speed unless a force acts on it. For an object to move in a circle, a force has to act on it all the time.This force is called the centripetal force. It acts towards the centre of the circle. Gravity is the centripetal force that keeps planets moving around the Sun, and satellites moving around planets.
Gravity is the universal force of attraction between masses. It provides the centripetal force needed to keep a satellite in orbit around a planet, or a planet in orbit around a star such as the Sun.
