give reason:
(1)A piece of paper takes much longer to fall than a stone through the same distance,when bothare dropped simultaneously from roof.
(2)the mass is constant everywhere whereas the weight keeps changing.
(3)the value of g keeps changing as we move away from the earth whereas value of G remains constant all over the universe?

Mass is the matter present in any substance which doens't changes with respect to any external force but weight depends on gravity so it keeps changing according to gravity applied on it.
Because G is universal gravitational constant which gives the attraction of any two objects kept at any distance from them. But g is dependent on mass of the two bodies and distance between them so if any one of them changes the value of g changes.
Hence when we increase the distance of body and earth the value of g becomes lower.
