I know this has been asked around, my question is a bit more specialized towards my personal problem.
If I have an object the magnitude of the weight is usually equal to the normal force, right?
I could be mistaken but from what I have read the normal force is the force the object is feeling opposite to the $(mass*gravity)$. If that is the case, and I put my hand on the object does my Force get added to the object's weight and thus the normal force of that object increases? Therefore if I keep adding hands to the object will the normal force keep compensating?
Also is the normal force the negative charged electrons repelling each other (electromagnetism)?
