About This Chapter
Overview of Forces - Chapter Summary
Work through this chapter at your own pace to get a comprehensive overview of forces in physics. As you progress through the chapter, you'll learn about various types of force, as well as friction formulas, Hooke's law and the spring constant. The chapter includes interactive self-assessment quizzes to help you practice solving force problems on your own. If you have any questions, simply submit them to our instructors online. For your convenience, you'll be able to access these resources at any time using your desktop, laptop or mobile device. When you're finished, you should be able to:
- Recognize the different types of force and friction
- Define the concept of normal force
- Use static friction and sliding friction formulas
- Explain the spring constant and Hooke's law
- Apply force and acceleration formulas to solve physics problems
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. 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.
3. Static Friction: Definition, Formula & Examples
In this lesson you will learn what static friction is and how it is different from kinetic friction. You will also learn a formula that can be used to calculate the force of static friction and see some examples of static friction in real life.
4. Sliding Friction: Definition, Formula & Examples
Sliding friction is different than static friction for most material combinations. Find out how it differs, when to apply this concept, and how to calculate the forces involved in this lesson.
5. Hooke's Law & the Spring Constant: Definition & Equation
After watching this video, you will be able to explain what Hooke's Law is and use the equation for Hooke's Law to solve problems. A short quiz will follow.
6. Practice Applying Force & Acceleration Formulas
In this lesson, we will introduce force and acceleration formulas using Newton's Force Laws and demonstrate kinematic equations, including examples, to solve real-world problems.
