Hey- could someone please help me with the free body diagrams. If there is a hand pushing on a book,laying on a table- what are the forces acting on the book? I thought they were normal force, force of hand and gravity.

OpenStudy (anonymous):

Consider the presence of a friction force as well. It will be directed opposite the force of the hand. Otherwise, the three you named is it.

OpenStudy (anonymous):

Will there be friction, if the hand is acting upon the book from above?
