Ch 51: TExES Physics/Math 7-12: Laws of Gravitation

About This Chapter

As part of your preparation for the TExES Physics/Mathematics, review the laws of gravitation and reinforce you understanding of Newton's and Kelpler's Laws to further increase you understanding of gravity.

TExES Physics/Math 7-12: Laws of Gravitation - Chapter Summary

In this chapter professional instructors review the laws of gravity, including those of the Newton and Kepler. Reinforce your knowledge of this force so that you can be prepared to answer questions on the Texas Examination of Educators Standards (TExES) Physics/Mathematics 7-12 about:

  • The Law of Universal Gravitation
  • Gravitational potential energy
  • Newton's laws of weight, mass and gravity
  • Kepler's laws of planetary motion
  • Elliptical orbits
  • Eccentricity

Further improve your knowledge of the laws of gravity by completing the lesson worksheets that accompany the lesson videos. Then discover areas of weakness by taking lesson quizzes. Return to the lesson videos to fortify these areas with video tags that are linked to key areas of the videos or read over the lesson transcripts. If at any time you come up with any questions, be sure to ask our instructors so that you can be prepared for related question on the TExES Physics/Mathematics 7-12.

TExES Physics/Math 7-12: Laws of Gravitation Objectives

Teachers in the state of Texas take the TExES Physics/Mathematics 7-12 certification exam to demonstrate their mastery over physics and mathematics before becoming certified. This computer based exam consists of 120 multiple choice questions and is administered in a five hour session. Of the material covered by the exam 39% of the questions are on topics of physics, including the laws of gravity. This chapter has been assembled to help you review the laws of gravity through a series of engaging lesson videos, worksheets and quizzes.

The Law of Universal Gravitation: Definition, Importance & Examples

1. 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.

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.

Newton's Laws and Weight, Mass & Gravity

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

Did you know that mass and weight are not the same? This lesson describes the difference between the two as well as the effect of gravity on weight. Examples are used to teach you how to calculate weight based on mass and acceleration of gravity.

Kepler's Three Laws of Planetary Motion

5. Kepler's Three Laws of Planetary Motion

Find out about the interesting life and major contributions of Johannes Kepler. This lesson will also teach you how to find out how long it takes a planet to revolve around the sun!

Elliptical Orbits: Periods & Speeds

6. 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

7. 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.
