WebGravitational accelerationcontributes to the total gravity acceleration, but other factors, such as the rotation of Earth, also contribute, and, therefore, affect the weight of the object. Gravity does not normally include the gravitational pull of the Moon and Sun, which are accounted for in terms of tidal effects. Variation in magnitude[edit]
WebAnswer (1 of 4): No, the gravitational constant being the same means that one unit of mass exerts the same amount of gravity everywhere. So a planet just like the Earth has the same gravity in the Andromeda galaxy or elsewhere. But a planet like Jupiter is not like the Earth. Its mass M is differ... WebIn physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag).This is the steady gain in speed caused exclusively by the force of gravitational attraction.All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies; the measurement …
