AP Physics 2: Newton's Laws of Motion - Chapter Summary
Use the lessons and quizzes in this chapter to review all three of Newton's Laws of Motion and apply your understanding to new examples of these laws. You can study the relationships between forces and how they apply to motion as you prepare for questions on the AP Physics 2 exam related to free-body diagrams, forces, and more. When you have completed this chapter, you should be able to:
- Provide examples of the First Law of Motion
- Explain how to use free-body diagrams to calculate force relationships
- Describe the Second Law of Motion
- Understand the principles of the Third Law of Motion
- Apply Newton's Three Laws of Motion to scenarios involving objects and forces
- List examples of the relationships between force pairs
- Categorize action and reaction force pairs
The lessons in this chapter are presented through short, engaging video lessons taught by professional instructors and are specifically designed to help you prepare for the AP Physics 2 exam. You can easily review specific ideas in the videos using the tagged points in the Timeline feature. There are also transcripts of the videos and self-assessment quizzes available with each lesson to enhance your learning.
1. Newton's First Law of Motion: Examples of the Effect of Force on Motion
This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.
2. Practice Applying Newton's First Law
This lesson introduces the reader to Newton's First Law, gives real world examples, and provides problems to show how we can use it to solve for unknown forces.
3. Practice Using Free-Body Diagrams to Calculate Balanced Forces
In this lesson, we'll tackle Newton's first law using free-body diagrams. Here, you'll get a better understanding of what Newton's third law means, as well as practice both drawing and interpreting free-body diagrams.
4. Newton's Second Law of Motion: The Relationship Between Force and Acceleration
This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.
5. Practice Applying Newton's Second Law
In this lesson, we'll look at the application of balanced and unbalanced forces in Newton's law in order to calculate the acceleration of different objects. We'll also practice calculating unknown forces, mass, and acceleration.
6. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces
This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.
7. Action and Reaction Forces: Law & Examples
Action force is force acting in one direction. Reaction force is force acting in the opposite direction. Learn more about Newton's Third Law as it explains action and reaction forces through several examples, and test your knowledge with quiz questions.
8. Identifying Action and Reaction Force Pairs
Good things often come in pairs, and forces are no exception. In this lesson you'll explore Newton's second and third laws of motion to understand how action and reaction pairs affect objects interacting with each other.
9. Practice Applying Newton's Third Law
This lesson will introduce the reader to Newton's Third Law and give real world examples. We'll also look at example problems that show how we can use Newton's Third Law and other equations to solve for unknown forces.
