Ch 31: Kepler & Newton's Laws of Motion

About This Chapter

With these lessons, you can gain a better understanding of Newton's laws of motion, weight, mass and gravity. You'll also take a look at Kepler's laws of planetary motion.

Kepler & Newton's Laws of Motion - Chapter Summary

This chapter can help you improve your understanding of Kepler and Newton's laws of motion and gravity. It uses short video lessons, taught by professional instructors, to explain:

  • Kepler's three laws of planetary motion
  • Newton's three laws of motion
  • Newton's laws of weight, mass and gravity
  • The law of universal gravitation

Each video lesson comes with a full written transcript for an alternative review. The self-assessment quizzes allow you to assess what topics you've mastered and what you still need to work on. Timeline tags let you quickly jump to specific areas of the lesson without having to view the video in its entirety. If you have any questions about the lesson material, you can submit them to our instructors via your personal dashboard.

Kepler's Three Laws of Planetary Motion

1. Kepler's Three Laws of Planetary Motion

Johannes Kepler, a German astronomer and a mathematician active in the 16th century, formed three laws of planetary motion. Learn about Kepler's life, his studying with the world's most respected astronomer at the time, Tycho Brahe, as well as Kepler's three laws of planetary motion.

Newton's First Law of Motion: Examples of the Effect of Force on Motion

2. Newton's First Law of Motion: Examples of the Effect of Force on Motion

Newton's first law, the law of inertia, states that an object will remain at rest or in motion unless acted upon by another force. Learn about whether Newton's first law applies to liquids or to human bodies, as well as whether it is applicable in space.

Newton's Second Law of Motion: The Relationship Between Force and Acceleration

3. Newton's Second Law of Motion: The Relationship Between Force and Acceleration

Newton's second law of motion is related to acceleration and force. Learn about net force, implications for this particular law of motion, and calculations for acceleration and force for moving objects.

Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

4. Newton's Third Law of Motion: Examples of the Relationship Between Two Forces

Newton's third law of motion states that forces come in pairs. Learn about how this law is applied in interactions between objects both on Earth and in space.

Newton's Laws and Weight, Mass & Gravity

5. Newton's Laws and Weight, Mass & Gravity

Gravity, which is the pull between two objects that have mass, is a force, which causes different objects to accelerate as they fall. Explore the differences between Newton's laws of weight, mass, and gravity, including how to calculate them, how gravity affects them, and how they are commonly misconceived.

The Law of Universal Gravitation: Definition, Importance & Examples

6. The Law of Universal Gravitation: Definition, Importance & Examples

The law of universal gravitation describes the important force between all objects in the universe. Explore the definition, importance and examples of universal gravitation and learn about Newton's apple.

Newton's Law of Gravitation: Definition & Examples

7. Newton's Law of Gravitation: Definition & Examples

This lesson explains how gravity works mathematically and teaches you how to use Newton's Law of Gravitation to solve problems. A short quiz will follow.
