Basics of Forces & Motion - Chapter Summary
If you're looking for ways to increase your understanding of forces and motion, this chapter can help! Fun lessons offer a comprehensive review of types of force and equilibrium, laws of motion and more. Refresh your knowledge of these science concepts by exploring the lessons at your own pace. Once finished, you will be prepared to do the following:
- Share the meaning of force, and identify its directions, sizes and types
- Differentiate between simple harmonic, linear, circular and projectile motion
- Discuss Newton's law of inertia and how force and motion interact
- Describe Newton's second law of motion and how force and acceleration relate
- Explain the relationship between two forces using Newton's third law of motion
- Detail how transitional and rotational equilibrium are used
Lessons in this chapter are accessible from any computer, smartphone or tablet. Navigate them in any sequence you choose to ensure your review of the basics of forces and motion suits your study and learning needs. If you want additional details about any lesson concept, feel free to submit questions to our experts. When ready, gauge your understanding of this chapter by taking short lesson quizzes and a chapter exam.
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. Motion: Linear, Simple Harmonic, Circular & Projectile
While you may be able to define 'motion' as it relates to science, do you know how simple harmonic, circular, linear and projectile motion differ from one another? Continue reading to find out more about these different types of motion, and then see if you can answer the questions on the follow-up quiz.
3. 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.
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. 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.
6. Equilibrium: Translational & Rotational
Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.
