About This Chapter
Force & Newton's Laws of Motion - Chapter Summary
With help from this chapter, get reacquainted with forces that impact the motion of an object, the relationship between force and motion and changes in the position and motion of objects subjected to an unbalanced force. Our lessons make it easy to understand Newton's three laws of motion and concepts of force, enabling you to do the following:
- Define and list types of force
- Discuss Newton's law of inertia and share examples of the effect of force on motion
- Explain Newton's second law of motion and the relationship between force and acceleration
- Share Newton's explanation of the relationship between two forces
- Provide the definition and an example of unbalanced force
As you review the lessons in this chapter, enjoy access to two fun formats designed to suit your unique study preferences. Lessons are available as engaging videos that average 8 minutes each or full transcripts you can read online or print to study while away from your computer or mobile devices. Multiple-choice quizzes ensure you fully understand the main topics of the lessons. Our practice exam gives you a broader review of this chapter to help you feel confident in your overall comprehension of force and Newton's laws of motion.
1. Force: Definition and Types
Force is everywhere and it comes in a variety of sizes, directions, and types. In this video lesson, you'll identify force as well the different types of force that objects may experience.
2. 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.
3. 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.
4. 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.
5. Unbalanced Force: Definition & Example
Unbalanced forces are forces that cause a change in the motion of an object. Learn more about how to identify balanced and unbalanced forces through several examples and test your knowledge with quiz questions.
