GRAVITATION AND WEIGHTLESSNESS
MEANING OF GRAVITATION
Gravitation is a force that has effect on the stability of a body. If an object is tossed up the air, it will fall back to the ground because the earth exerts an attraction on it. This attraction is called gravitational attraction.
The gravitational attraction / force between any two object increases as the two objects approach each other.The earth has a great gravitational pull because it has a great mass. The gravitation pull of the earth is always directed to the centre.
Weightlessness is a feeling of being weightless. It does not mean having no weight. As someone move away from the surface, it progressively reduces. In the outer surface of the earth, a person or body has no weight because the gravitational pull of the earth is no longer acting there.
