negative gravitational mass
1Negative mass — In theoretical physics, negative mass is a hypothetical concept of matter whose mass is of opposite sign to the mass of the normal matter. Such matter would violate one or more energy conditions and show some strange properties such as being… …

7Gravitational energy — is the energy associated with the gravitational field.According to classical mechanics, between two or more masses (or other forms of energy momentum) a gravitational potential energy exists. Conservation of energy requires that this… …
8Mass versus weight — The chains on the swing hold all the child’s weight. If one were to stand behind her at the bottom of the arc and try to stop her, one would be acting against her inertia, which arises purely from mass, not weight. In everyday usage, the mass of… …
9Gravitational binding energy — The gravitational binding energy of an object consisting of loose material, held together by gravity alone, is the amount of energy required to pull all of the material apart, to infinity. It is also the amount of energy that is liberated… …
10Gravitational shielding — The term gravitational shielding refers to a hypothetical process of shielding an object from the influence of a gravitational field. Such processes, if they existed, would have the effect of reducing the weight of an object. All experimental… …
