# Ch 7: Laws of Motion

View this chapter's video lessons to study Newton's laws of motion. Review concepts like inertia, gravity and mass. Explore the kinds of friction as well as the types of forces that can act upon objects.

## Laws of Motion - Chapter Summary

Use the fun video lessons in this chapter to refresh or improve your understanding of Newton's three laws of motion. Our professional instructors explain these important laws and give examples to help you grasp the concepts. You'll also study mass, velocity, gravity and air resistance. The lessons cover topics such as inclined planes, friction and balanced and unbalanced forces as well. In addition to explaining the principles behind Newton's laws of motion, you should be able to do the following after completing the chapter:

• Distinguish between mass and inertia as well as mass and weight
• List the types of forces and friction
• Interpret free-body diagrams
• Calculate net force
• Determine an object's acceleration and the forces acting upon it
• Explain the relationship between Newton's laws and weight, mass and gravity
• Identify action and reaction force pairs
• Give examples of the normal force in action

There are several physics concepts to cover in this chapter, but our short video lessons break them down in an entertaining way. We offer multiple features with our lessons to make your study time more effective. Video tags allow you to easily review key points without having to rewatch entire lessons. If you want to study Newton's laws in written form, we provide transcripts of our videos as well. Once you're ready, take the multiple-choice lesson quizzes to check your comprehension of the material.
