Assume if we had a 2 tonne weight placed on ground attached with a rope that we can use to turn the object around. It will immensely hard to turn that object around by pulling the rope. However, if the weight was lifted to a certain height by a crane, when we try to turn that weight around; the force and the work is very low compared to the force needed to move the same object when it is on the floor.
Why is this?
Does the earth gravitational pull affect the amount of force required to turn the object?
