Now suppose we are considering the gravitational attraction between two bodies (as we always are), one of mass m 1, one of mass m 2. If the distance between them is 7m, find the mass. Gravitational force decides how much we weigh and how far a ball travels when thrown before it lands on the ground. After students response: explain to them that : The weight of an object will decrease because the gravitational force acting on an object is called weight There is less gravitational force on the object at a place away from the surface of earth as compared to that on the surface of the earth. 10-45. is the most effective force over long distances. !
