You are right and wrong. Yes, when you pull something, you are pushing on it too. But that doesn't mean "when you pull something you actually are pushing on it". That just means "you must push something while pulling it". Look at my scheme below. +--------------------------> PULL | v PUSH +--------------------+ | OBJECT | +--------------------+ ^ PUSH | +--------------------------> PULL Why must we push something while pulling it? Because we must make a friction between the puller (say, our finger) and the object. Have you learnt the vector and the Newton laws? I'll tell you more if you have learnt them. KW
