Uncle, why does our bookshelf always stay on ground.
That's because of GRAVITY dear...
Well gravity is a very complex term, but in easy way its an invisible force that pulls everything on ground.
What is gra.. gra.. vity uncle ?
Oh! Now I understand.
Um.. people think that there is no gravity in space but little amount of gravity can be felt in space as well.
Come lets go inside and talk more about it...
Uncle then why does everyone float in the space?? Is there no gravity out there?
Uncle, now I am wondering that who discovered this great power?
Very good question! Gravity was discovered by Sir Isaac Newton. There is a story behind it...
What the story uncle?
Um.. So one day Sir Isaac Newton was relaxing under an apple tree. All of a sudden an apple falls on his head...Seeing the apple, he wonders that why does this apple fall straight down and doesn't went up? So he researched a lot about this and discovered GRAVITY..
Now I have to leave.. Hope you enjoyed learning about gravity! Also don't forget to wear mask and sanitize your hands regularly.
