Inertial Navigation: A Bridge between Kinematics and Calculus

Those who come to Cambridge soon learn that the fastest route between Harvard and MIT is by the subway. For many students, this short ride is a quick and easy way to link physics and calculus. A simple, homemade accelerometer provides all the instrumentation necessary to produce accurate graphs of acceleration, velocity, and displacement position on this subterranean route. Each graph, in turn, reveals a story of the train's trip: speeding up and braking, varying track conditions, top speed, and the distance between subway stops deep beneath Massachusetts Avenue. (Contains 4 figures.)
