What is Physics? - Definition, History & Branches

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.

Math Review for Physics: Algebra

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.

Math Review for Physics: Trigonometry

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.

Elements of the SI: Base & Derived Units

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.

The Metric System: Units and Conversion

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.

Unit Conversion and Dimensional Analysis

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.

Significant Figures and Scientific Notation

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.

Linear & Direct Relationships

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.

Quadratic & Inverse Relationships

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.

How to Do Volume Conversions

10. How to Do Volume Conversions

Did you know that, by using a special number, you can convert from feet to meters? You will learn what this special number is in this lesson. You'll also learn what other special numbers there are for converting between other units.

How to Convert Ounces to Liters

11. How to Convert Ounces to Liters

In this lesson, we will learn how to convert ounces to liters using a simple conversion process. We will then look at multiple examples of applying this process in real world situations.

How to Convert Liters to Gallons

12. How to Convert Liters to Gallons

This lesson will teach you how to convert liters to gallons in a couple easy steps, how to check your work in one of two different ways, and how this can be applied to the real world.

How to Convert mL to Gallons

13. How to Convert mL to Gallons

In this lesson you will learn how to convert milliliters into gallons using the relationships between the metric system, the U.S. customary units, and the British imperial units.

Converting Quarts to Gallons: How-to & Steps

14. Converting Quarts to Gallons: How-to & Steps

In this lesson, you will learn how to convert from quarts to gallons using the U.S. customary system of measurements and the British Imperial system of measurements.

How to Convert Ounces to Gallons

15. How to Convert Ounces to Gallons

This lesson offers step by step instructions for converting U.S. ounces into gallons. You'll also learn how to convert from the Imperial (U.K.) ounce to gallon measurements as well.

How to Convert Ounces to Cups

16. How to Convert Ounces to Cups

Converting from ounces to cups is a relatively easy process. That's what we'll look at in this lesson, as well how to convert the other way round. Finally, we'll see how the conversion process lends itself to real world situations.

How to Convert Stone to Pounds

17. How to Convert Stone to Pounds

In this lesson, we will learn how to convert stone to pounds using a very simple conversion factor. We will also see how we can convert pounds back to stone as well.

Physics of Resonance: Tacoma Narrows Bridge Collapse

18. Physics of Resonance: Tacoma Narrows Bridge Collapse

The Tacoma Narrows Bridge is famous for collapsing in a spectacular fashion during a windstorm. In this lesson, you'll dive into the physics of this collapse by learning about resonance frequency and what that has to do with the bridge's downfall.
