Ch 8: Laws of Motion in Physics

About This Chapter

Study the motion of objects in this action-packed physics chapter. Use these exciting lessons to deepen your understanding of the amazing world of forces and how objects react to them.

Laws of Motion in Physics - Chapter Summary

Our experts are ready to show you why Newton's Three Laws of Motion explain the actions and reactions of all objects in the universe. Each law is described and demonstrated in its own engaging video lesson. Through these lessons, you will learn about the relationships between forces and how these relationships contribute to changes in motion. You will also explore the connections between weight, mass, and gravity and the role these factors play in Newton's Laws.

By the end of the chapter, you will be ready to identify examples of Newton's Laws of Motion all around you. Mastering this topic means that you are able to:

  • Explain and list examples of Newton's First Law of Motion
  • Model the relationship between force and acceleration
  • Demonstrate and explain Newton's Third Law of Motion
  • Differentiate between mass and weight
  • Explain how mass, weight, and gravity affect motion
  • Explain and apply Hooke's Law

Each lesson in this chapter is presented through a short informative video. To review main points or examples from a lesson, use the Timeline feature of the player to jump to specific tagged sections of the video. To enhance your learning, all lessons are accompanied by a self-assessment quiz and a lesson transcript. Use these features to review your understanding and determine your level of mastery of this physics topic.

Newton's First Law of Motion: Examples of the Effect of Force on Motion

1. 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.

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

2. 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.

Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

3. 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.

Newton's Laws and Weight, Mass & Gravity

4. Newton's Laws and Weight, Mass & Gravity

Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.

Hooke's Law & the Spring Constant: Definition & Equation

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.
