Graphs and Tracks Revisited
Peer reviewed Peer reviewed
Direct linkDirect link
Christian, Wolfgang; Belloni, Mario – Physics Teacher, 2013
We have recently developed a Graphs and Tracks model based on an earlier program by David Trowbridge, as shown in Fig. 1. Our model can show position, velocity, acceleration, and energy graphs and can be used for motion-to-graphs exercises. Users set the heights of the track segments, and the model displays the motion of the ball on the track…

Measuring the Velocity of a Tennis Serve.
Peer reviewed Peer reviewed
Eng, John; Lietman, Thomas – Physics Teacher, 1994
Presents an alternative to the use of a radar to determine how fast an individual can serve a tennis ball. Equipped with a tape recorder and a Macintosh computer, students determine the velocity of a tennis ball by analyzing the sounds and echoes heard on the court. (ZWH)
