Ch 5: Praxis Physics: Motion

About This Chapter

Use this chapter to review the laws and properties of motion in physics. A firm understanding of the content of these lessons will help you when you're taking the Praxis Physics test.

Praxis Physics: Motion - Chapter Summary

These lessons will address the basics of motion on which you may be tested during the Praxis Physics test. In addition to explaining inclined planes and torque, this chapter addresses the following:

  • Newton's first, second, and third laws of motion
  • Static equilibrium
  • Forces of friction
  • Uniform circular motion
  • Centripetal force requirement

You will be led through this chapter by expert instructors who aim to explain the information in a clear manner. If you have any questions, though, you may submit them to our physics experts who will help as they are able. After you finish studying all the lessons, take the cumulative chapter exam, which will help gauge how well you understand what you've reviewed and help you determine what you need to study further.

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.

Inclined Planes in Physics: Definition, Facts, and Examples

4. Inclined Planes in Physics: Definition, Facts, and Examples

If an object is not horizontal to the ground, it may be on an inclined plane. We need to adjust both the calculations and the free-body diagram when determining the net force on an object on an inclined plane. Learn how in this lesson.

Torque in Physics: Equation, Examples & Problems

5. Torque in Physics: Equation, Examples & Problems

After watching this video, you will be able to explain what torque is and use an equation to calculate torque in simple situations. A short quiz will follow.

Static Equilibrium of Rigid Bodies

6. Static Equilibrium of Rigid Bodies

What is static equilibrium? Learn about the factors that cause an object to remain stationary, without translating or rotating. Then take a quiz to make sure your understanding hasn't remained static.

What is Friction? - Definition, Formula & Forces

7. What is Friction? - Definition, Formula & Forces

Friction is the force that opposes the motion of an object. Learn about the sources of friction, identify examples of friction and test your knowledge with quiz questions.

Uniform Circular Motion: Definition & Mathematics

8. 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.

The Centripetal Force Requirement: Definition, Examples & Problems

9. The Centripetal Force Requirement: Definition, Examples & Problems

What keeps a roller coaster in a loop? Learn about centripetal force, what causes a centripetal force, and how to calculate it. Complete a quiz to test your knowledge.
