The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ 0 or ɡ n, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is a constant defined by standard as 9.806 65 m/s 2 (about 32.174 05 ft/s 2).
4 lis 2012 · Acceleration of Gravity is one of the most used physical constants - known from Newton's Second Law "Change of motion is proportional to the force applied, and take place along the straight line the force acts."
The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
Near Earth's surface, the acceleration due to gravity, accurate to 2 significant figures, is 9.8 m/s 2 (32 ft/s 2). This means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.8 metres per second (32 ft/s) every second.

Newton ’s Universal Gravitational Constant G = 6.67 x 10-11 N.m2/kg2. The Sun has a mass of 1.99 x 10 30 kg, and a radius of 6.96 x 10 8 m. The Moon has a mass of 7.35 x 10 22 kg, aradius of 1738 km., and an average orbital radius of 3.84 x 10 5 km., and orbital period of 27.3 days.
22 mar 2018 · Over time, scientists were able to put a value on the acceleration due to earth’s gravity as 9.81 m/s 2. Mathematically the equation for g is: g = G *Me/ r2. g = acceleration due to gravity (units m/s2) G = the universal gravitational constant, G = 6.673 x 10-11N·m2kg2. Me = mass of a large body (for example, Earth).
