Suppose we have a very heavy object resting on a frictionless floor. If we pull upwards without moving it, what happens to the force we are applying?
I am a bit confused regarding normal forces in this case too. If someone could help me out by clearing this doubt, specially including normal terms, I would really be grateful.
I understand the sum would be zero, but in which direction does the normal force act. If you consider pushing the object downward then normal force by the floor would act on the object upward. (which would be equal to the weight of the object and the force we applied), due to action reaction force. I want to know,if we are pulling the object up, in which direction does the normal force act? Downwards probably, but how can that be.?? A free body diagram would help.
