Ch 7: GED Science - Mechanics: Help and Review

About This Chapter

The Mechanics chapter of this GED Science Help and Review course is the simplest way to learn about mechanics. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of mechanics.

Who's it for?

Anyone who needs help learning or mastering GED science material will benefit from taking this course. There is no faster or easier way to learn GED science. Among those who would benefit are:

  • Students who have fallen behind in understanding Newton's laws of motion or mechanics
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about mechanics
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the mechanics chapter exam.

Why it works:

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the mechanics chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any mechanics question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

Students will review:

This chapter helps students review the concepts in a mechanics unit of a standard GED science course. Topics covered include:

  • Speed and velocity
  • Acceleration
  • Newton's first, second and third laws of motion
  • The law of universal gravitation
  • Simple machines

9 Lessons in Chapter 7: GED Science - Mechanics: Help and Review
Speed and Velocity: Concepts and Formulas

1. Speed and Velocity: Concepts and Formulas

Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.

What is Acceleration? - Definition and Formula

2. What is Acceleration? - Definition and Formula

This lesson describes the difference between speed, velocity and acceleration. Examples are used to help you understand the concept of acceleration and learn to calculate acceleration with a mathematical formula.

Implications of Mechanics on Objects

3. Implications of Mechanics on Objects

Forces act on objects causing them to move. Mechanics is the field of science designated to the study of moving objects. This lesson describes how forces act on objects resulting in motion. Examples are used to describe how forces interact resulting in both simple and complex movement.

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

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

This lesson describes Newton's first law of motion, also known as the law of inertia. The interaction between force and motion is explained. Several examples are used to discuss the implications of this law on earth and in space.

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

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

This lesson defines Newton's second law of motion. Examples are used to illustrate how unbalanced forces cause objects to accelerate. The examples are used to practice calculating acceleration and force for objects in motion.

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

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

This lesson describes Newton's third law of motion. Examples are provided to illustrate how interacting objects experience forces. The lesson explains how objects accelerate as a result of force. Applications of Newton's third law are illustrated in nature, machines, and space.

Newton's Laws and Weight, Mass & Gravity

7. 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.

The Law of Universal Gravitation: Definition, Importance & Examples

8. 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.

What Are Simple Machines? - Definition, Types & Examples

9. What Are Simple Machines? - Definition, Types & Examples

If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.
