The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
The same equation used to determine the value of g on Earth' surface can also be used to determine the acceleration of gravity on the surface of other planets. The value of g on any other planet can be calculated from the mass of the planet and the radius of the planet.
Sep 25, 2024 · Gravity is measured by the acceleration that it gives to freely falling objects. At Earth ’s surface the acceleration of gravity is about 9.8 meters (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 meters per second.
Sep 23, 2024 · Gravitational constant, physical constant denoted by G and used in calculating the gravitational attraction between two objects, which is equal to G times the product of the masses of the two objects divided by the square of the distance between them. The value of G is 6.6743 x 10^-11 m^3 kg^-1 s^-2.

Of the four known forces of nature, gravity is the strongest on large scales - it has an ability to lock planets, stars and galaxies in their orbits. On small scales however, gravity appears to act much weaker than its counterparts. Nevertheless, gravity is something we can measure here on Earth.
Oct 11, 2024 · The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
The size of the gravitational attraction between two bodies increases in proportion with their masses, diminishes with the square of the distance between them, and has an absolute value ultimately...
