This attraction is called gravitational attraction.<br \/>\nThe gravitational attraction \/ force between any two object increases as the two objects approach each other.<br \/>\nThe earth has a great gravitational full because it has a great mass. The gravitation pull of the earth is always directed to the center.<br \/>\nWEIGHTLESSNESS<br \/>\nWeightlessness is a feeling of being weightless. It does not mean having no weight.
