Question

why earth move around its axis and don't tell centripetal centrifugal force​

Answer 1

Answer:

If you will think carefully...

Then see... you know planets are formed by crushing of rocks or we can say by collision of two rocks which are formed by heat and dust.

And another thing to notice is that the collision makes the planet to move and you know in vacuum there is no external force hence whenever a body is moved it will remain in that state itself.Hence earth moves on its axis....just an imagination of mine
