Kinetic Theory describes the random motion of atoms.
There are 4 assumptions of the theory (hyperphysics] (http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/kinthe.html) ): 1. A large number of molecules are present, but the space they occupy is also large and keeps the individual molecules far apart (as Rutherford proved: here ), 2. The molecules move randomly, 3. The collisions between molecules are elastic and therefore exert no net forces, and 4. The molecules obey Newtonian mechanics.

The examples of kinetic theory include Brownian Motion- the random movement of dust particles because of collisions with "air" molecules and how gases behave i.e. Boyle's, Charles', and Gay-Lussac's Laws. Also, this theory explains how temperature affects the states of substances.
