Question

Newton's Universal Law of Gravitation: plz explain in simple words​

Answer 1

$\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}$

It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.

Answer 2

Answer:

Newton's UNIVERSAL LAW OF GRAVITATION says that -

'Every object (no matter very small or very big) in the Universe attracts (pulls towards itself) every other object with a DEFINITE FORCE.'

'This Force is DIRECTLY PROPORTIONAL to the product (×) of masses of the two objects and INVERSELY PROPORTIONAL to the SQUARE OF THE DISTANCE between them.'

You know that,

everytime we take 'F' for force, 'm' for mass of object, 'd' for distance.

You also know the sign of proportianality.

Directly proportional = @ , Inversely Proportional = @ 1/

:. According to Definition,

F @ m1 × m2. - (since two objects are there, :. mass is m1 and m2)

F @ 1/d^2. - (Inversely Proportional)

*Combine both equations*

F @ m1 × m2 / d^2

:. F = G m1 m2 / d^2. - ( We remove @ by adding a 'CONSTANT' )

( 'G' is UNIVERSAL CONSTANT OF GRAVITATION )

:. F = Gm1m2

-----------

d^2
