About Physicsway

Physicsway offers free, concise, and easy-to-read notes for introductory college courses. The notes cover algebra-based physics — Physics 1 and Physics 2 — along with the algebra that supports them, and are written to be clear and to the point, with worked examples, figures, and animations.

The site also includes an interactive virtual lab — a simulation of the Newton's second law experiment — and step-by-step Excel tutorials for graphing and data analysis.

PageScan for iPhone

PageScan is a free iPhone app from Physicsway that turns handwritten homework into a clean PDF in three taps. It finds the edges of the page, straightens it, and drops out the shadows, so what you hand in looks like a scan rather than a photo of a desk.

It is built for handwritten work: pencil stays visible, paper comes out white, and the letters stay solid black. Scan as many pages as the assignment needs, name the file, and share it straight to Google Classroom, Canvas, Mail, or Files.

There is no account, no advertising, and no cloud — nothing ever leaves your phone. PageScan does not solve your homework; it only scans it.
