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 is creating a collection of videos and
materials. Most of the videos on
this site were made for the project.
