Momentum, Energy, and Collisions
The collision of two carts on a track can be described in terms of momentum conservation and,
in some cases, energy conservation. If there is no net external force experienced by the system of
two carts, then w

Introduction:
The photoelectric effect is the name given to the phenomenon in which light
incident on a photosensitive material causes electrons to be ejected from its surface.
