Motion Analysis of a Rocket-Propelled Truck.
Peer reviewed Peer reviewed
Hitt, Darren L.; Lowe, Mary L. – Physics Teacher, 1996
Describes an experiment to study the motion of a rocket-propelled vehicle over the entire duration of the engine burn using a video system with a frame-by-frame playback and a Sonic Ranger for ultrasonic position movements. Enables students to study the impulse-momentum principle and the effects of a time-varying force. (JRH)
