## Who's it for?

This chapter of our high school physics tutoring solution will benefit any student who is trying to learn about introductory physics and earn better grades. This resource can help students including those who:

- Struggle with understanding the basics of physics, math for physics, the metric system, significant figures, scientific notation, linear and direct relationships, quadratic relationships or any other introductory physics topic
- Have limited time for studying
- Want a cost effective way to supplement their physics learning
- Prefer learning physics visually
- Find themselves failing or close to failing their introduction to physics unit
- Cope with ADD or ADHD
- Want to get ahead in high school physics
- Don't have access to their physics teacher outside of class

## Why it works:

**Engaging Tutors:**We make learning about introductory physics simple and fun.**Cost Efficient:**For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.**Consistent High Quality:**Unlike a live physics tutor, these video lessons are thoroughly reviewed.**Convenient:**Imagine a tutor as portable as your laptop, tablet or smartphone. Learn introductory physics on the go!**Learn at Your Pace:**You can pause and rewatch lessons as often as you'd like, until you master the material.

## Learning objectives:

- Define physics and explore its history.
- Review the fundamentals of trigonometry and algebra.
- Describe the elements of the SI base.
- Discover how to use the metric system.
- Learn the rules for converting among mass, volume, density, temperature and length.
- Use scientific notation and significant figures.
- Discuss direct, linear, 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. How to Convert Parsecs to Light Years

In this lesson, we define and relate two very important distance measures: the parsec and the light year. These measures are typically used for describing the immensely long distances between astronomical objects. We'll learn how to convert from parsecs to light years.

### 11. Converting Arcseconds to Parsecs

After reading this lesson, you'll learn how to convert your arcseconds to parsecs using a very simple process. Learn what the steps are and then see it in action.

### 12. Converting Parsecs to Meters

In this lesson, you'll learn how to convert a parsec measurement to meters. You'll learn the conversion number you need to use to make the conversion and the simple steps to follow.

### 13. How to Convert 800 Meters to Miles

In this lesson, we will learn how to convert meters to miles in general, and then we will use this process to convert 800 meters to miles. We will also talk about the fact that this value is normally rounded and the reason why.

### 14. How to Convert Centimeters to Inches

It's easy to make conversions of length. In this lesson, you'll learn how to easily convert from centimeters to inches. You'll also see what number to use for the conversion and how to use it.
