# Ch 17: Praxis General Science: Newton's Laws & Motion in Physics

Building expertise in physics is necessary if you want to earn a teaching certification in general science. Get ready for the Praxis General Science examination by watching this chapter's educational online video lessons on Newton's laws.

## Praxis General Science: Newton's Laws and Motion in Physics - Chapter Summary

Brush up on physics concepts in preparation for passing the Praxis General Science examination. As you pursue a teaching certification, look at this chapter's video lessons on Newton's laws of motion. You can review examples of acceleration and force, and recall or learn applications for Newton's first, second and third laws of motion. Continue watching the lessons and discover how to determine net force or calculate an object's weight based on its mass. When you finish the chapter, you might be able to:

• Explain Newton's first, second and third laws of motion
• Define gravity, and contrast weight and mass
• Convert between weight and mass
• Note the differences between mass and inertia
• Identify and give examples of inclined planes

Study these physics principles and examples and find out how much you remember from your college classes. Teacher-led, animated and self-paced, the video lessons are informative, fun, and convenient. The chapter includes worksheets, transcripts and lesson summaries. Usually, the educational videos are no longer than eight minutes in length. They're followed up by quizzes that contain five multiple-choice questions. Use these to gauge your comprehension and your preparedness for corresponding questions on the Praxis General Science examination for a teaching endorsement.
