About This Chapter
Force, Mass, & Newton's Laws of Motion - Chapter Summary
These lessons explore Isaac Newton's laws of motion, as well as concepts such as force and mass. You'll study the applications of Newton's laws and understand the differences between units of measurement like weight and mass. The chapter is designed to make the learning process simple and easy. Practice quizzes are included to help you check your understanding of the material as you work your way through the chapter, and our expert instructors are available to answer questions whenever you need clarification. You can access this chapter on any computer or study on-the-go using your tablet or mobile device. These lessons will teach you things like:
- What Newton's first, second and third laws of motion state
- What the formula for acceleration is
- Understanding the mathematics behind uniform circular motion
- Applying Newton's Law of Gravitation
- Differences between mass and weight
- Naming the types of force
- How to calculate net force
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. 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. What is Acceleration? - Definition and Formula
This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.
5. 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.
6. 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.
7. Uniform Circular Motion: Definition & Mathematics
After watching this lesson, you will be able to explain what uniform circular motion is, in terms of both acceleration and forces. You will also be able to use equations for centripetal force and acceleration to solve problems. A short quiz will follow.
8. Newton's Law of Gravitation: Definition & Examples
This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.
9. Mass and Weight: Differences and Calculations
We often talk about mass and weight as if they are the same. While they are proportional to each other, they are not, in fact, the same. In this video lesson, you will learn to distinguish between the two, as well as convert one to the other.
