   Every motion study has these three components:
  • Moving Object(s) (e.g. falling or colliding objects, an athlete's run, etc.)
  • Instruments for recording the motion
  • Method of analyzing the data

Described in the following pages is a study of momentum conservation in collisions
   Two HO-gauge model railway cars are caused to collide;
   The collision is recorded on digital video tape; and
   The video is captured, and can be displayed frame by frame and analyzed using currently available sofware
