QS In what direction does the tension force always point? Q9 Why is the tension force always a pull and never a push? Q10 Tension is transmitted through a rope or cable by forces acting on both ends of the rope or cable. Why do we not identify (or give different labels to) the tension force on each end separately? Perpendicular to a Surface: Normal Force, FN Activity 4 A book resting on a table does not move. According to ewton's First Law, the net force on the book must be zero since the book is not moving. The force that explains why books do not fall through tables is called the normal force FN. It is a perpendicular contact force exerted by a surface. In the drawing at the right, a book is sitting on the table. The book is not moving, so the net force on it must be zero. FN Fg Q11 How does the table “know" how much normal force to exert as the weight of the object placed on top of it changes?
