Gravitational field strength, g

A definition for gravitational fields is a region in which objects with mass experience a force.

The strength of a gravitational field is defined as the force, F, acting on a unit mass, m, in the field which in an equation is:

g= F/m

Symbol: g. Units: newtons per kilogram, Nkg-¹, which is the same as ms-².

Uniform field

In a uniform field, g will remain constant. You can consider the Earth’s gravitational field to be uniform as long as you don’t move more than a few kilometres above the surface of the Earth. On the surface of the Earth, g = 9.81Nkg-¹, of course.

Newton was the first person to fully explain gravitational fields. He came up with the following equation for field strength in a radial field:

g = Gm/r²

where

g = field strength

G = the universal gravitational constant, value 6.7x10-11 Nkg-²m²

m = the mass of the object in the field

r = the separation between the centres of the mass and the object causing the field.

The derived unit for gravitational field strength is N (newton), being the unit for force. The base unit equivalent kg m / s^2 (kilogram meters per second per second)

What wrong with you kids nowadays go read Ur book lol

(g )= Gravitational field strength (newton)/(kilogram)
N/Kg= (kg·m/s²)/Kg
=
m/s² (Base units)

(Well I think? I am getting old)
