The value of the net force depends upon the magnitude and direction of each of these forces. Newton’s First Law, the Law of Inertia, states that a net force of zero causes an object to be at rest or in motion with constant velocity. The purpose of this lab activity is to investigate each of these cases.

Solution: The net force for case A is For case B its magnitude is For case C we must add the components: Finally, the net force in case D is 3 N. Therefore, the ranking of the accelerations, from smallest to greatest, is: A < D < B < C. Insight: The question could be answered without any calculation. First we note that the net force in case A ...
