Question:
In a weightless environment, an object would spin by its centre of gravity, why does this not happen on earth.


Replies:
It does- If you were to take a wrench or some other object and locate its CG then drop it off of a building and photograph it in free fall you would find that the object spins about its CG during the fall. In other words the path of the CG would be straight.
