Specific gravity is the ratio of a substance's density to the density of a reference substance, usually water for liquids, or air for gas. For example, since the density of iron is about 8 times as much as that of water, that means that its specific gravity is 8.
its gravitiy
35kg
The Sun spins because of Gravitiy!
theres gravity on every planet
we would all die because there is no gravitiy
Sir Isaac Newton.
You are weihgtless in space because there less gravitiy up there

Thurst, Gravitiy, Potential Energy, Kinetic Energy, and a few other.
Both kinetic and potential energy vanish.
the law of gravitiy will reverse
Gravitational waves propagate at the speed of light. Any change in the distribution of masses will propagate at that speed.
