Friends, in this article I have discussed about the behavior of the gravitational force.
Sir Isaac Newton had proposed the Law of Gravitation after many observations. In this law, he claimed that the gravitational force is an unseen force and its magnitude depends upon the masses of the objects ( between which the force acts ) as well as the distance of separation between these two objects. However, the force is inversely proportional to that distance of separation i.e. force will decrease as we move farther away from the object.
Can we find a point at where the net gravitational force due to an object is zero? Well, the gravitational force decreases rapidly as we move away from the objet. But, it will never zero rather consistently act to some degree no matter how we go. The Sun attracts Mercury stronger than Pluto. Sun's attraction force doesn't become zero beyond Pluto. It also continuously attracts numerous smaller icy bodies that move around it in huge orbits.
But the astronauts doesn't feel the attraction force of the earth in a spacecraft (like ISS). A a result, they move freely ( without experience any kind of force) inside a spacecraft. Although they have remained at a close distance to the earth as compared to the size of its.
If we observe deeply, we will find that the gravitational force of earth acts upon the spacecraft as well as on the astronauts that present inside it. Due to which they continue to fall to the earth's orbit.
