About This Chapter
Who's It For?
Anyone who needs help learning or mastering introductory physics material will benefit from the lessons in this chapter. There is no faster or easier way to learn introductory physics. Among those who would benefit are:
- Students who have fallen behind in understanding the history of physics and key math skills related to the field
- 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 introductory physics
- 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 Introductory Physics 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 Introductory Physics chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any introductory physics 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 an introductory physics unit of a standard physics course. Topics covered include:
- The branches of physics
- Algebraic and trigonometric math skills
- The International System of Units (SI)
- Units in the metric system
- Unit conversion
- Scientific notation
- Graphs of linear and direct relationships
- Inverse and quadratic relationships
1. 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.
2. 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.
3. 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.
