About This Chapter
Newton's Laws of Motion and Gravitation - Chapter Summary
This chapter's lessons offer a review of Newton's three laws of motion and their implications. Our instructors will also explain how they can be used to determine weight and mass. You'll learn about the law of universal gravitation and why it is important. After watching these videos, you should understand:
- Newton's first law of motion and inertia
- Newton's second law of motion and acceleration
- Newton's third law of motion and force
- What Newton's law of universal gravitation states
- Applications of Newton's law of universal gravitation
Our lessons are available whenever you have a few minutes to devote to study, on the computer or via your mobile device. After completing each lesson, take the multiple-choice quizzes that accompany them to test your knowledge. If you have questions, feel free to contact the instructors. They're happy to help.
1. Overview of Newton's First Law of Motion
Ever cursed the fact that your car wouldn't come to a stop as quickly as you might wish? Or, wonder how you get the dirt off your shoes when you kick them against a post? Well, wonder no more! Newton's first law of motion explains it all!
2. Overview of Newton's Second Law of Motion
Have you ever had to push a broken-down car? Hopefully, the answer is no but if you have, you definitely know that the lighter the car, the easier the job. In this lesson, we learn why that is the case.
3. Overview of Newton's Third Law of Motion
Ever felt the recoil of a paintball gun? Or, hurt your hand after hitting a wall? Surely you've breathed, right? In this lesson, we explain Newton's third law of motion, which makes all of those possible.
4. Measuring Mass & Weight With Newton's Laws
If you thought that learning Newton's Laws of Motions was only useful to pass a physics test, think again! In this lesson, we'll learn how to use them to calculate mass and weight, two related but different concepts.
5. The Law of Universal Gravitation: Definition, Importance & Examples
Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.
