SUMMARY The goal of Chapter 6 has been to learn how to solve problems about motion in a straight line. General Strategy All examples in this chapter follow a four-part strategy. You’ll become a better problem solver if you adhere to it as you do the homework problems. The Dynamics Worksheets in the Student Workbook will help you structure your work in this way. Equilibrium Problems Object at rest or moving with constant velocity. MODEL Make simplifying assumptions. VISUALIZE •Translate words into symbols. Identify forces. Draw a free-body diagram. SOLVE Use Newton’s first law: “Read” the vectors from the free-body diagram. ASSESS Is the result reasonable? F r net 5 a i F r i 5 0 r Dynamics Problems Object accelerating. MODEL Make simplifying assumptions. VISUALIZE •Translate words into symbols. Draw a sketch to define the situation. Draw a motion diagram.
