About This Chapter
OAE Physics: Laws of Gravitation - Chapter Summary
Enjoy your study sessions with these entertaining video lessons that examine the forces of gravity. Brush up on how the laws of gravity work as you study for the OAE Physics test. After you go through all of the chapter, you should feel more comfortable answering test questions related to the following:
- Law of universal gravitation
- Kepler's laws
- Centripetal force
- Newton's laws
- Eccentricity and elliptical orbits
- Gravitational attraction
Don't let the weight of the OAE Physics test throw you off your game. You've likely already covered these topics in school, and our brief refresher can quickly re-familiarize you with the laws of gravitation. Our instructors work diligently to break up dense subject matter into smaller, manageable lessons that you can master in minutes. Full transcripts are also available in case you prefer to read the lesson or want to skim through for key vocabulary words. As an added bonus, our instructors are available should you have any questions on the lesson material.
OAE Physics: Laws of Gravitation - Chapter Objectives
The licensure process for physics teachers in Ohio includes passing a subject-specific assessment, the OAE Physics test. The test is only given on computers, and test-takers 225 minutes to provide responses to 150 multiple-choice questions. To determine if teachers have a comprehensive understanding of physics, the test has been broken up to cover five of the most predominant related fields of study. The mechanics of physics section, where gravitation questions reside, represents 28% of the entire assessment. Motion and gravitation are fairly significant topics within the mechanics of physics section, so you can expect a fair amount of questions directed at these areas.
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.
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.
3. 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.
4. 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.
5. 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.
