acceleration due to gravity

Hi Friends,

Let us learn about "acceleration due to gravity"

To introduce the concept of "Acceleration due to gravity", We’ll discuss "g" further below but we must understand a few concepts -–for example, mass:

The acceleration that an object experiences because of gravity when it falls freely close to the surface of a massive body, such as a planet. Also known as the acceleration of free fall, its value can be calculated from the formula

g = GM / (R + h) ²

where M is the mass of the gravitating body (such as the Earth), R is the radius of the body, h is the height above the surface, and G is the gravitational constant (= 6.6742 × 10^-11 N·m²/kg²). If the falling object is at, or very nearly at, the surface of the gravitating body, then the above equation reduces to

g = GM / R ²

In the case of the Earth, g comes out to be approximately 9.8 m/s² (32 ft/s²), though the exact value depends on location because of two main factors: the Earth's rotation and the Earth's equatorial bulge.

In our next blog we shall learn about "integral energy"

I hope the above explanation was useful.Keep reading and leave your comments.
