Many students are unable to distinguish clearly between momentum and kinetic energy and to recognize which is conserved in specific situations

    A moving glider on a linear air track collides with a stationary glider, thus giving it some momentum. This datalogging experiment explores the relationship between the momentum of the initially moving glider, and the momentum of both gliders after the collision.

    The event can also be described in terms energy transfer.
