# Ch 8: Praxis Physics: Linear Momentum

Get ready to earn a teaching certification in physics. This chapter and its lessons highlight linear momentum, which is covered on the Praxis Physics assessment. Explore these lessons and use the included quizzes to determine how much you've learned.

## Praxis Physics: Linear Momentum - Chapter Summary

Prepare to answer questions about linear momentum on the Praxis Physics examination. When you begin studying this chapter's animated video lessons, you'll explore the fundamentals of linear momentum. As you progress through the chapter, Newton's laws of motion and the law of conservation of momentum will be explained along with elastic and inelastic collisions. Upon completion, you could be capable of:

• Defining and understanding linear momentum
• Determining the effects of impulse on momentum
• Explaining and giving examples of the law of conservation of linear momentum
• Describing the principles behind elastic and inelastic collisions
• Understanding isolated systems

Since the video lessons are short, often between five and ten minutes in length, they can be added to your existing study resources. You can review them online at your convenience as you prepare for the Praxis Physics examination. The lesson instructors provide much of the information you'll need to address questions on the above topics during the testing process. Take the handy quizzes when you're ready, and refer to the transcripts when you need quick clarification. There are also video tags that will allow you to quickly find facts.

### Praxis Physics: Linear Momentum Chapter Objectives

The Mechanics section is, by far, the largest of the Praxis Physics examination's six content categories. It has 40 questions and makes up about 32% of the assessment score. The topics that you've studied here will show up on the test. These include impulse and momentum, elastic and inelastic collisions, Newton's laws and conservation of momentum. All 125 test questions are in selected-response format. You'll have 2.5 hours to finish the computer-based test and, potentially, qualify for a teaching license in physics.
