Ch 13: Chapter 13: Universal Gravitation

About This Chapter

The Universal Gravitation chapter of this Prentice Hall Conceptual Physics Companion Course helps students learn the essential physics lessons of universal gravitation. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Universal Gravitation textbook chapter.

How It Works:

  • Identify the lessons in Prentice Hall Conceptual Physics' Universal Gravitation chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the universal gravitation topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Law of universal gravitation
  • Newton's formula for the force of gravity
  • Earth's gravitational pull and its applications
  • Types, causes and effects of tides
  • Schwarzschild black holes and the event horizon
  • Big Bang theory and the origin of the universe

Sir Isaac Newton And Astronomy

1. Sir Isaac Newton And Astronomy

This lesson will teach you about Newton's laws of motion and universal gravitation as well as why the moon doesn't fly off into space and why it doesn't crash into the Earth.

The Law of Universal Gravitation: Definition, Importance & Examples

2. 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.

Isaac Newton's Formula for the Force of Gravity: Definition & Example

3. Isaac Newton's Formula for the Force of Gravity: Definition & Example

Watch this video lesson and you will see how you can calculate the force of attraction between two objects. Learn why our planets don't spin themselves out of orbit around the sun.

Gravitational Pull of the Earth: Definition & Overview

4. Gravitational Pull of the Earth: Definition & Overview

Earth's gravitational pull is often misunderstood, but without it, life on Earth would be impossible. In this lesson, we'll define the gravitational pull and give some examples of how it is used. A quiz is provided to test your understanding.

What Are Tides? - Causes & Effects

5. What Are Tides? - Causes & Effects

Tides rise and fall under the influence of the gravitational pull of the moon and sun. Learn about different tides, why they are predictable and their effects on coastal regions of the world.

Black Holes: the Event Horizon and Schwarzschild Radius

6. Black Holes: the Event Horizon and Schwarzschild Radius

This lesson describes the event horizon and the Schwarzschild radius, including their implications on the gravitational attraction a black hole exerts on the universe around it.

Origins of the Universe: The Big Bang and Expanding & Contracting Universes

7. Origins of the Universe: The Big Bang and Expanding & Contracting Universes

Students will learn the origins of the universe, the Big Bang theory, the timeline of the universe, how the universe is still expanding to this day, and what astronomers expect the universe to look like in the future.
