Matter and Energy: Kinetic and Potential Energy / Fission and Fusion

Beginning with the Universe as an enormous system of matter and energy, we see examples of properties and states of matter the relationships between kinetic and potential energy and the role of energy in chemical changes. The Law of Conservation of Matter and energy, as related to nuclear fission and fusion, leads to the modern concept of the equivalence of matter and energy. Film flickers a bit between 1:00 and 1:53.
