moon gravitational field
1Gravitational 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… …

6Gravitational wave — In physics, a gravitational wave is a fluctuation in the curvature of spacetime which propagates as a wave, traveling outward from a moving object or system of objects. Gravitational radiation is the energy transported by these waves. Important… …
7Gravitation of the Moon — The gravitational field of the Moon has been determined by the tracking of radio signals emitted by orbiting spacecraft. The principle used depends on the Doppler effect, whereby the line of sight spacecraft acceleration can be measured by small… …
8Hollow moon — The hollow moon theory is a pseudoscientific theory that suggests that Earth s moon is a large hollow sphere. Little published evidence exists to support the idea.Seismometer recordings from November 1969 are often cited as evidence against this… …
9History of gravitational theory — In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times.AntiquityIn the 4th century BC, the Greek philosopher… …
10Orbit of the Moon — Not to be confused with Lunar orbit in the sense of a selenocentric orbit, that is, an orbit around the Moon The Moon completes its orbit around the Earth in approximately 27.3 days (a sidereal month). The Earth and Moon orbit about their… …
