You learned that different types of forces act on objects directly and indirectly you also learn what happens when forces are balanced and unbalanced examine the diagram below showing forces acting on a box. 1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box what will be the net vertical force on the box.
3. What force could be applied to the box to make the net force in the horizontal direction zero? explain.
4. Suppose a force of 25 N to the right is added to the box. what will be the net force to the right?
