Combining this equation with the equation for the universal law of gravitation we obtain, g= GM/r2. Thus the force of gravity depends on the mass of the body and is inversely proportional to the square of the distance r. Weightlessness When an astronaut is floating in space, they feel ...

the planet will move to D, forming the blue triangle (Newton’s first law). We know that these two triangles have the same area. However, it turns out that the planet moves inward a little bit, due to gravity, and forming the yellow triangle. Kepler told us that the yellow...
Based on Newton’s Law of Gravitation, why is the gravity on the moon so different from the gravity on the Earth? If there is another planet with a larger mass than the Earth and it originally started at a distance from the moon equal to the distance that the Earth is from the moon,...

Even in the unimodular Einstein gravity, the Newton law is reproduced but the mechanism is a little bit different from that in the unimodularF(R) gravity. We also investigate the unimodularF(R) gravity in the covariant formulation. In the covariant formulation, we include the three-form field...
