Abstract
In their article “Measuring the Flight Speed of Fire Bombers from Photos: An In-Class Exercise in Introductory Kinematics,” Greg W. Lowe and Eric Ayars1 remind us that photographs have always had physics hidden in them if you look hard enough. Since digital photos are embedded with EXIF data, vastly more physics can be explored with them. EXIF stands for “exchangeable image file format” and is data that are recorded into a photo when it is taken with a digital camera. Table I shows various methods for finding the EXIF data of a photo. I use one piece of this data to begin my unit on rotational motion.
