Introducing Rotational Motion with EXIF Data
Peterson, James
Physics Teacher, v49 n7 p440-441 Oct 2011
In their article "Measuring the Flight Speed of Fire Bombers from Photos: An In-Class Exercise in Introductory Kinematics," Greg W. Lowe and Eric Ayars 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.
