Unit 6: Gravitation (Hindi)
About this unit
Why do things fall down to earth but not the moon? Why are you not flying away from your chair? Will a feather fall to earth first or a brick? Let's explore more about Gravitation and find answers to these question.Why are you sticking to your chair (ignoring the spilled glue)? Why does the earth orbit the sun (or does it)? How high could I throw my dog on the moon?
Gravitation defines our everyday life and the structure of the universe. This tutorial will introduce it to you in the Newtonian sense.

Until this lesson, we have always assumed the gravitational field is uniform and potential energy is equal to mgh. Now we'll learn how to find the gravitational potential energy at large distances when these assumptions no longer hold.
