A Practical Example Aiding Understanding Momentum in 1D: The Water Gun Experiment
MacLeod, Katarin
Physics Education, v42 n5 p492-495 Sep 2007
The law of conservation of momentum is one that students often have difficulties understanding. This experiment allows students to use childhood toys to examine and calculate the muzzle velocity of their favourite water gun by using an air track, a spark timer or data logger and the law of conservation of momentum in a one-dimensional case, a modification of the standard ballistic pendulum laboratory experiment (1990 "Physics 100 Lab Manual" St Francis Xavier University). (Contains 7 figures.)
