A Measure of "g": In Search of Simplicity
Ganci, Alessio; Ganci, Salvatore
Physics Education, v45 n3 p223-224 May 2010
In the study of kinematics it is often emphasized that freefall time is independent of particular parabolic trajectory, provided that the initial velocity is parallel to the horizontal plane. There are various experiments to prove features of freefall in textbooks and other literature. Using a PC one can make precise measurements of time intervals with programs such as Creative Wave Studio. This article presents a classroom experiment wherein a teacher can illustrate these freefall features and measure "g" using zero-cost apparatus. (Contains 2 figures.)
