Mj-5 Interatomic Force Model


To demonstrate a model that illustrates the inter-atomic force.


  • Linear air track
  • Compression spring

Interatomic Force Model Setup.


The air track is inclined at a small angle and a compression spring attached to one end of the track. A glider placed on the air track experiences the gravitational force of attraction at large distances of separation and a strong repulsive force when in close proximity to the atom (binding post).
