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. 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.
4. 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.
5. 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.
6. Scientific Notation: Practice Problems
Scientific notation has a lot of exponents, but it's really not that bad - and it's really convenient for working with awkwardly big or small numbers! Get some practice here.
7. Practice with the Metric System, Significant Figures & Scientific Notation
This lesson will introduce the reader to the metric system, significant figures, and scientific notation. Additionally, we will use those three components as a way to do metric system conversions.
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.
