Calculation of Acceleration due to Gravity on Earth
Acceleration due to gravity, g = (G ×M)/r2
Here, G is the gravitational constant, M is the mass of the Earth, and r is the radius of the Earth.
We know,
G = 6.674×10-11 m3/kg/s2
M = 5.972 × 1024 kg
r = 6.371 × 106m
Putting these values into the formula to calculate g, we have :
g = {(6.674 × 10-11) × (5.972×1024)}/ (6.371 × 106)2
This calculation gives the value of g as approximately 9.81 m/s².
Value of g
The acceleration felt by a free-falling object due to the gravitational force of the mass body is called gravitational acceleration. It is denoted by g and calculated using SI unit m/s2. The value of g depends on the mass of the body and its size. Its value varies from body to body. In this article, we will learn about the value of g in physics in detail.
