• Resumen

  • Before the advent of microcomputerbased labware MBL, �timeofflight� measurements1,2for the speed of a transverse pulse on a string required elegant apparatus. This paper describes how to use an offtheshelf MBL force sensor and a computer to perform the measurement. The data shown in this paper were collected using Vernier Softwares wireless dynamics sensor system and Logger Pro software,3but almost any common force sensor coupled with a computer or graphing calculator should work. You will also need about 2 m of string or elastic cord4and a meterstick or tape measure.
