The above acceleration is due to the gravitational pull of earth so we call it acceleration due to gravity, it does not depend upon the test mass. Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.
How is g calculated?
The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.
What is g in the formula of force?
Gravitational Force Formula
The little g stands for the amount of acceleration that is caused by gravity. This is what is commonly referred to as g-force. The big G is the Newton's gravitational constant, approximately 6.67 x 10-11 N * m2 / kg2.
What is Big g in physics?
The gravitational constant is familiarly known as "big G" to distinguish it from "little g," the acceleration due to the Earth's gravity.
