The Newtonian Physics

| |

Gravity is rather a special force which is unusual which is different from many other forces like electrical forces , etc.
And is somewhere connected with geometric properties of space and time which has a great impact to the brain of our great scientist Sir Albert Einstien.
Here, in this post we gonna talk about the working of a great man on two historical terms.Which was named as………

                                        The Newtonian Physics
                    (A introduction to general theory of relativity)

Ok, now we know the two terms Newton for which he is really famous for but I would like to take a part of it and want to reavel the real concepts and story behind the origination of a historical formula
                                        F=G m1 m2 / R2

well you wanna more about NEWTON (click on this)
THE STORY BEGINS..............

The cellestial bodies like moon the earth, the subject of great intrest for every one of those scientists related to astronomy.

"I am proud to be an indian". why????

Because, the famous indian astronomer Arayabhatt studied these motions in great detail.Which he compiled in his book in Arayabhatt. He compiled in his book in circular motions pf every celestial body.

Then about after 1000 years. the brilliant combination of Tycho brahe and Johnan Kepler brought their formulation of three law of planetery motion
* 1st law (law of orbit)-

According to this all the planets revolve on an celestial path with a fixed focus placed on sun.

*2nd law (law of area)

According to this law all the planets revolve around the sun covers an equal area with respect to the radius vector
therefore it implies a case that is ......

*3rd law (law of periods)

the square of the time period of a planet is propotional to the cube of the semimajor axis of the eclipse.

that was all a base for the next section of the story......

The year 1965 was one of the best part in the life of Newton and I would like to give title to that year
                                 "THE FRUITFUL YEAR"
the yeaar made him think about focusing his attention towards the motion of the moon about the earth.
now let see what he thought.

Yes, it was all about the acceleration of the body around us.

The first question of newotn's mind ask......
                                   what is the force that produces this

He came with a natural guess that actually earth is attracting the moon
now,the existing fact about newton-
that newton was sitting under an apple tree when an apple fell down from the tree on the earth .That sparked the idea that earth is attracting the apple down .

Have, you noticed that both the incidents are related to the study of accleration.

Newton come upon with some daring assumption which proved to be turning points in science and philosphy for every upcoming minds.
Let's see what happened next-

The acceleration of a body falling by the earth is equal to 9.8m/s

                      distance of the moon from the earth
                       distance of the apple from the earth
well guys lets have some conclusion form this.
the acceleration is inveresely propotional of the square of the distance between them
                and we know  F=m.a
so we can say,

And it is atated in thied law of motion that,
                                      the force on the earth due to the
                                       body must be equal to the force
                                        on the earth due to the body
so, now here comes the revolotionary fomula,
or,                                F=Gm1m2/r2

the constant G is known as the universal constant of gravitation and its value was formulated to be 6.67*10-11

that's finishes the real story behind the mind game of NEWTON.
