Worked example. Calculate the magnitude and direction of the resultant force in the diagram below. Step 1: Add up all of the forces directed to the right. 4 N + 8 N = 12 N. Step 2: Subtract the forces on the right from the forces on the left. 14 N – 12 N = 2 N. Step 3: Evaluate the direction of the resultant force.

Working Definition of Force. Dynamics is the study of the forces that cause objects and systems to move. To understand this, we need a working definition of force. An intuitive definition of force—that is, a push or a pull—is a good place to start. We know that a push or a pull has both magnitude and direction (therefore, it is a vector ...
