Collisions in Two Dimensions |
Using this one apparatus your students can study the concepts of momentum and kinetic energy in elastic and inelastic collisions. A curved ramp delivers a steel ball to the collision with constant energy. The different ranges of the ballsÍ trajectories in steel to steel and steel to glass collisions account for the different energy and momentum results. Includes two 1/2" steel balls, a 1/2" glass ball, and a 1" wooden plumb bob. Requires C-Clamp, sold separately.
WARNING: CHOKING HAZARD - This toy is a small ball. Not for children under 3 yrs.

- Friday, February 11, 2011 Collision in 2-D Reviewed By: Nickey (Plainfield, Illinois) The track pictured in the catalog works fantastically with low % of error. The one currently being shipped was changed by the vendor and is not worth ordering. The current model has a track mounted on plexiglas. You swivel the track instead of altering the position of the target sphere as pictured in the catalog. The set-up pictured in the catalog withstood the roughness of large group of inquisitive teens. This one does not. You have to C-champ it to your lab table and ensure that once this is done, there is no movement. The metal plate was better suited for this and didn't crack or chip.
