Cellular Phones Helping To Get a Clearer Picture of Kinematics

摘要

The main purpose of this paper is to add to the list of examples of how cell phones may be used as teaching tools in the classroom.'One very interesting example of this comes fromthe study of projectile motion, the classical "cannonball" problem. This problem is central to the studyof kinematics, the very first topic a student meets inphysics. Our approach exploits the fact that thesedays almost all students carry cellular phones and thevast majority of the phones have built-in cameras.
