Learning Introductory Physics with Activities

Chapter 5 Interacting Systems

We will now build quantitative models for the most common forces.
Learning Outcomes
After successful completion of this chapter, you will be able to:
  1. Construct net force equations in multiple dimensions for multiple objects or systems based on acceleration and free-body diagrams
  2. Solve net force equations symbolically in terms of given variables
  3. Identify Newton’s third law force pairs
  4. Analyze systems of massive objects and pulleys of negligible mass using a force approach
