Newton's Law of Gravitation

* Newton's law of universal gravitation expressess that the gravitational force between two object is the attractive force which its magnitude is directly proportional to the mass of each object and inversely proportional to the square of the distance between that centers. Mathematically it si written as follows.

$F_{}g=G\frac{m_{1}m_{2}}{r^{2}}$

* The Value of universal gravitation constant (G) was first determined by Henry Cavendish by using Cavendish's torsion, that is $G=6.6754\cdot 10^{-11} Nm^{2}/kg^{2}$

* Gravitational field strength or gravitational acceleration is the gravitational force per mass unit of an object. Mathematically, is writen as follows.

$\fn_cm g=\frac{F}{m}=\frac{GM}{r^{2}}$
