When two vectors are facing the same direction and are on the same axis ( both vertical or both horizontal ) they can be to find the sum . When two vectors are facing opposite directions and are on the same axis ( both vertical or both horizontal ) they should be . If two vectors are not on the same axis , you must use to find the sum . If a person pushes an object to the left with 10N of force and someone else pushes an object to the left with 15N of force , the total force is to the . If a person pushes an object to the right with 40N of force and someone else pushes an object to the left with 25N of force , the total force is to the .
