About This Chapter
Who's it for?
Anyone who needs help learning or mastering high school physics material will benefit from taking this course. There is no faster or easier way to learn about high school physics. Among those who would benefit are:
- Students who have fallen behind in understanding the metric system and SI base units or basic physics calculations
- 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 physics
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How it works:

Students will review:
This chapter helps students review the concepts found in an introductory unit of a standard high school physics course. Topics covered include:
- SI base units
- The metric system
- Unit conversion
- Dimensional analysis
- Significant figures
- Scientific notation
- Direct and linear relationships
- Inverse and quadratic relationships
1. What is Physics? - Definition, History & Branches
Known as the fundamental science, physics creates a foundation for other natural sciences. In this lesson, you'll be introduced to the field of physics, learning about its history and its modern branches of study.
2. Math Review for Physics: Algebra
There's quite a lot of algebra you need to know to do physics. Here we'll review some of the concepts needed for rearranging equations, working with polynomials, and working with exponents.
3. Math Review for Physics: Trigonometry
This lesson reviews some basic trigonometry that is essential for an introductory physics course. Here we'll focus on the various methods for finding side lengths and angle measurements of a right triangle.
4. Elements of the SI: Base & Derived Units
Discover what we mean by SI units. Then explore SI units further by learning about all the base units, and several examples of the derived units that make up the system.
5. The Metric System: Units and Conversion
Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.
6. Unit Conversion and Dimensional Analysis
How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.
7. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
8. Linear & Direct Relationships
Learn how to tell when you're dealing with linear and direct relationships and what graphs of these relationships should look like. Then, go further and explore how to interpret the slopes of these graphs.
9. Quadratic & Inverse Relationships
Explore how we tell when two variables are in quadratic or inverse relationships in this lesson. Once you understand the basics, we'll go over a couple of examples where these relationships show up in a physics class.
10. Calculating Center of Mass: Definition, Equation & Example
What is the center of mass and how is it calculated? Is it the same as the centroid or center of gravity? Learn how to find the center of mass of objects in one-, two-, even three-dimensional space!
