Tour of Physlets: Example 2


This example shows how Animator can be used to simulate a collision between a projectile and a tethered mass. The collision is dynamic. That is, the two particles interact via internal interactions rather than according to an analytic trajectory. The collision is constructed so that this interaction between the masses is perpendicular to the lever arm of the constrained mass, thereby conserving angular momentum about the pivot. This simulation can be used as an effective in-class Peer Instruction or an out-of-class JiTT problem to determine if students understand that free particles carry angular momentum.
