AP Physics 1: Newton's Third Law of Motion - Chapter Summary
The lessons in this chapter can help you thoroughly prepare for questions about Newton's third law of motion on the AP Physics 1 exam. This comprehensive review spans Newton's third law as it relates to weight, mass and gravity, as well as the types of friction. Upon completion of this chapter, you should have the knowledge to:
- Give examples of the relationship between two forces
- Identify action and reaction force pairs
- Define normal force and give examples
- Utilize inclined planes in physics
These lessons on motion have been prepared by experienced instructors, and you can move from lesson to lesson at your convenience. You also have the ability to assess your knowledge of the topics covered by utilizing the lesson quizzes and chapter exam at the end.
1. 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.
2. Newton's Laws and Weight, Mass & Gravity
Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.
3. 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.
4. The Normal Force: Definition and Examples
The normal force is also called the contact force because it only exists when objects are touching. In this lesson, we will investigate what the normal force is and how to calculate it on flat and inclined surfaces.
5. Friction: Definition and Types
You experience friction all the time, and you should be glad you do! Friction helps keep stationary objects in place as well as slow moving objects down as they slide across a surface. This lesson identifies what friction is and explains the two ways we find this force on earth.
6. Inclined Planes in Physics: Definition, Facts, and Examples
If an object is not horizontal to the ground, it may be on an inclined plane. We need to adjust both the calculations and the free-body diagram when determining the net force on an object on an inclined plane. Learn how in this lesson.
