Question

What is Newton's law of Gravitation? Explain​

Answer 1

Answer:

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers

Answer 2

Newton's Law of Gravitation-

This law of gravitation states that each particle present in the universe attract all the other particles with a force which is

(i) Directly proportional to product of their masses

$F \propto \: m_{1} \times m_{2}.....(1)$

and

(ii) Inversely proportional to its square of distance between them.

$F \propto \frac{1}{ {r}^{2} } .......(2)$

From (1) and (2)

$F \propto \frac{m_ {1}\times m_{2}}{ {r}^{2} }$

On removing proportionality

$\boxed{F = G \frac{m_{1}m_{2}}{ {r}^{2} } }$

where

G is universal Gravitation Constant

F is the force

r is the distance between them

m1 and m2 are the masses.

Note- This law can be applied only on spherical symmetry bodies or point masses.
