Chapter 3 Forces
We will now begin a new topic, perhaps the most foundational in all of physics: Forces.
Learning Outcomes
After successful completion of this chapter, you will be able to:
- Differentiate between contact forces and non-contact forces
- State and apply Newton’s laws
- Draw a free-body diagram of an object or multiple objects in a system
- Define the normal force acting on an object in various situations
- Define tension in a system
- Construct net force equations in multiple dimensions for an object based on its acceleration and its free-body diagram
- Solve net force equations symbolically in terms of given variables
- Include friction force acting between two objects at rest or in motion
- Identify Newton’s third law force pairs
- Analyze systems of massive objects and pulleys of negligible mass using a force approach
