Short videos, often just 20 to 30 frames in length, can be extremely useful in teaching physics and other sciences. Not still photographs, but too short to be considered movies, these "live photos" are designed for analysis in a computer. Positions of objects in the video frame can be measured by pointing a mouse and clicking. The data can be graphed, analyzed in spreadsheets, compared to theoretical models, and even used to display vectors or points superimposed on the original video.

The LivePhoto Physics Project published a collection of videos and classroom-tested curricular materials. Some of the videos on this site were made for that book.
