Three questions arose to me:
The first is what is responsible for the earth spinning? Is this just newton's first law in action - having been formed out of the material in the cluster of clouds after the big bang the world just remained in circular movement?
The second - are there any known planets that do not rotate on their axis?
The third - what is responsible for the objects on earth to spin with the earth to that rotation is left unnoticed? Is it the gravitational force of the earth that, as the objectד on earth have radial velocity the gravitation pull gives the objects a circular motion, which incidentally is the same as the the earths rotation?
