How Reflected Wave Fronts Dynamically Establish Hooke's Law in a Spring
Fahy, Stephen; O'Riordan, John; O'Sullivan, Colm; Twomey, Patrick
European Journal of Physics, v33 n2 p417-426 Mar 2012
A simple benchtop experiment in which a moving cart collides with a fixed spring is described. Force-time and force-distance data recorded during the collision display the transit of compression wave fronts through the spring following impact. These data can be used by students to develop a computational model of the dynamics of this simple mass-spring-sensor system using a simple application of the wave equation and thereby develop an intriguing picture of how a spring realizes Hooke's law approximately in this dynamic physical problem. (Contains 5 figures.)
