Extension paragraphs

Many paragraphs in the Essential Physics eBook contain a "more" button after the last sentence, as shown below. Clicking this button opens an extension paragraph with additional text, animations, or video. This additional content serves to extend or enhance the ideas in the preceding paragraph, allowing interested students to delve deeper into areas of physics that intrigue them.

Hover your mouse over a "more" button to view a floating window with a brief description of the extension paragraph's contents. To close an extension paragraph after reading it, select the "less" button at the end of the extension paragraph.

Some of these extension paragraphs contain content which is included in the lists of technology, engineering, and math connections. Content in the extension paragraphs can also be found using the index and the search function.

Note

Extension paragraphs are not found in the printed textbook.
