TExES Science 7-12: Laws of Gravitation - Chapter Summary

This Laws of Gravitation chapter of the study guide provides an introduction to gravity and its effects. Lesson topics include Newton's law of gravitation, gravitational attraction, and potential energy. Other topics covered in this chapter are Kepler's laws of planetary motion and elliptical orbits. You should better understand the following by the end of this chapter:

  • Application of Newton's law of gravitation
  • Gravitational attraction of extended bodies
  • Understanding gravitational potential energy
  • Application of Kepler's laws of planetary motion
  • Periods and speeds of elliptical orbits
  • Eccentricity and orbits of planets

Our expert instructors lead short, entertaining lessons and are available to answer questions if needed. Use the self-assessment quizzes to determine if you need additional study. The timeline feature makes it easy to return to key points in the lessons for review.

Newton's Law of Gravitation: Definition & Examples

1. 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.

Gravitational Attraction of Extended Bodies

2. Gravitational Attraction of Extended Bodies

After watching this lesson, you will be able to explain what an extended body is, understand the derivation for the force of gravity between a point charge and a long, thin bar and solve problems using the result of that derivation.

Gravitational Potential Energy: Definition, Formula & Examples

3. Gravitational Potential Energy: Definition, Formula & Examples

In this lesson, you will learn what gravitational potential is, the equation we use to calculate it, and how to use that equation. We'll look at some real-life examples so you can see how it works. A short quiz will follow.

Kepler's Laws, Ellipses, and Eccentricity

4. Kepler's Laws, Ellipses, and Eccentricity

This lesson will discuss Kepler's First Law of Planetary Motion; define an ellipse, focus, major axis, semimajor axis, and eccentricity; and explain what they have to do with astronomy.

Elliptical Orbits: Periods & Speeds

5. Elliptical Orbits: Periods & Speeds

After watching this lesson, you will be able to explain what an elliptical orbit is and calculate the period and speed of an object in an elliptical orbit, if given enough information. A short quiz will follow.

Eccentricity & Orbits of Planets

6. Eccentricity & Orbits of Planets

After watching this lesson, you should be able to explain what eccentricity is and calculate the eccentricity of an orbit given relevant distance measurements. A short quiz will follow.
