Do Newton Discover the Gravitation by finding the reason why apple fall from the Tree ?

When we think of gravity then the first thing comes in mind of why and how objects fall to the earth. But as we go to the discovery of gravity then there are so many stories behind this . As we All know that previously it is believed that all the planets revolve around the earth. But some great astronomers said after that No All planets revolve around the sun not the earth . Many of the People don't believe them as that theory was very contradictory theory.

Contribution of Classical Physicist

 Galileo Galilei made some contribution in this and helped to make the whole picture more clear. Like he told that the acceleration of the free falling body does not depend on mass of the body.(There is a story of leaning tower of Pisa involved in this discovery).  Then after that Newton came into the play and made laws of gravitation .Newton figure out how moon and earth revolution take place and discover about the fundamental law of gravitation. 

Drawback of Newton law of gravitation

When Newton formulated the laws of gravitation he always wondered to a question that A body change its state(Rest to motion and vice versa) when a unbalanced force is applied on it . And that body accelerate by that applied unbalanced force . So when a body fall downwards then what pushing it downwards and how it's acceleration is constant. 

This question stunned him . He actually don't know the answer of this question but he invented a new force called gravitational force which somehow give a satisfactory answer of this question .But many Physicists don't agree to his theory and that question became a problem and was unsolved for many years. 

Einstein New theory of Gravity

After so many years Einstein tried to solve that problem and came out with a new Theory of gravity . Which actually tells about so many amazing things like 4D space time fabric, Gravity bends light and many more . That led to discovery of modern gravitational theory . Einstein theory was largely accepted in the physic community.(I will tell you about this theory  later )

Conclusion

As the title of the blog says did the story was true ? 

But as far as I know The story was not true that Newton discovered the laws of gravitation by wondering how a apple fall.

But he get to know About a question to which he don't have any answer so for correcting his theory he invented a new force called gravitational force. 

But it was Einstein who truly visualized the theory of gravitation and formed a new Theory .

Disclaimer

I am not saying that Newton theory is wrong . Both Newton Theory and Einstein Theory are correct. Einstein's is  more accurate. Newton's is Simpler and give sufficiently accurate results for most usage . Both theories are correct only with different complexities and accuracy.
