One Dimensional Collision Model 1.0

This interactive simulation allows students to collide two objects and investigate whether momentum and/or kinetic energy are conserved in the collision process. To keep things simple, the simulation involves an isolated system where the objects collide along a single line. Use the sliders to set mass of both objects, initial velocity, and elasticity: then watch the resulting collision. Students then calculate post-collision values for momentum and kinetic energy for both balls.<br /><br />SEE ANNOTATIONS for a link to an editor-recommended online tutorial on conservation of momentum, part of The Physics Classroom collection. <br /><br />Editor's Note: Lots of factors are at play, even in a simple collision. This resource will help your students build understanding the of following: 1) How to apply the law of momentum conservation, 2) Total energy in a closed system (it's always conserved, but in collisions, kinetic energy is generally transformed into other forms of energy), 3) In special cases (perfectly elastic collisions) the kinetic energy stays the same before and after a collision, 4) In completely inelastic collisions, objects stick together, 5) momentum is a vector.<br /><br />This resource is distributed as a ready-to-run (compiled) Java archive. In order to modify the simulation (and see how it is designed), users must install the Easy Java Simulations Modeling and Authoring Tool.
