This chapter is full of informative resources that simplify the process of units of understanding and measurement in physics. Review short video and text lessons to learn concepts that include scientific uncertainty, unit modification, and size analysis. When you have completed this chapter, you will be able to:
- Define SI units, and describe basic and customized units
- Describe the features of scientific estimates
- Explain the importance of accuracy and precision in science and how you can avoid uncertainty when making estimates
- Discuss the basics of size analysis and unit modification
Choose one, several, or any number of courses you can review based on your current and desired unit knowledge and measurement in physics. Review any lesson as often as you can to fully absorb the information you are reviewing. Before, during, or after examining the lessons, take multiple-choice questions to measure your understanding. If you need more information on any of the course topics, feel free to send your questions to our experts.
