How acceleration due to gravity value is calculated?

Answer 1

The acceleration of gravity due to a single object is

(Universal gravitational constant) x (Mass of the object)/(distance from the object's center of mass)2

Answer 2

The acceleration due to gravity on Earth is typically calculated using the formula: ( g = \frac{GM}{r^2} ), where ( G ) is the gravitational constant, ( M ) is the mass of the Earth, and ( r ) is the distance from the center of the Earth to the object. The standard value for acceleration due to gravity on Earth is approximately ( 9.81 , m/s^2 ).
