Adding Forces: 5 N. Random Object. 5 N. Notice that all the new forces are pointed in the same direction, and they add together! So, instead of only 5N of force pushing the object; now there are 10 N of force pushing! Multiple forces can combine to move an object that has too much inertia for one force alone. The forces "add together"!
