Explain briefly about  Newton's law of gravitation

Answers (1)

Newton's law of gravitation-

According to Newton's law of gravitation, the gravitational force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Due to gravitational force, Each particle in this universe attracts every other particle.

The direction of this force is along the line joining the particles. 

Let two particles of masses m_1 and m_2 separated by a distance r exert  a Force F on each other

And Magnitude of F is given as  

                                                   F\; \alpha\; \frac{m_{1}m_{2}}{r^{2}}

 

                               Or,   F\; = \frac{G\, m_{1}\, m_{2}}{r^{2}}

 

Where

F\rightarrow Force    

G\rightarrow Gravitational constant

m_1,m_2\rightarrow  Masses

r\rightarrow  Distance between masses
