About This Chapter
Understanding Types of Force - Chapter Summary
How is force defined? What are the forces of nature? These are just some of the topics you will find details about when you refer to the lessons in this chapter.
You will also learn about important terms, calculations and effects related to force. Once you have completed your review of this chapter, you should be able to:
- Define force and identify different types of force that impact objects
- Apply calculations to determine net force
- Differentiate between balanced and unbalanced forces
- List and explain the four fundamental forces of nature
Video lessons are accessible from any device 24/7, making it possible to study when and where it works best for you. You can also print lesson transcripts to create handy reference materials to use when you do not have Internet access. Lesson quizzes help you determine if you fully understand one topic before you go to the next.
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. Net Force: Definition and Calculations
Because forces are vectors, we can't simply add them up to get a total amount of force on an object. Instead, we calculate the net force, which is important to understand because it tells us about an object's state of motion.
3. Forces: Balanced and Unbalanced
Forces are needed to start or stop an object's motion, but can also be involved when an object is at rest or already traveling at constant velocity. In this video lesson, you'll identify the difference between balanced and unbalanced forces, understanding how they affect the movement of objects.
4. The Four Fundamental Forces of Nature
In this lesson, we'll learn about the four fundamental forces of nature. We will define them and then describe some of the surprising ways in which they affect the world around us every day.
