2. Kinetic Energy – Energy of Motion Potential Energy – Energy of Position (stored energy Forms of Energy

4. Kinetic Energy

5. First Law of Thermodynamics  Energy can be transferred or transformed but it cannot be created or destroyed

6. Second Law of Thermodynamics  Every energy transfer or transformation increases the entropy of the Universe

7. Nuclear Fission  Isotopes with large mass numbers are split by being struck with a neutron which releases energy and more neutrons

8. Nuclear Fusion  Two light isotopes are forced together at high temperatures to form a heavier nucleus and releases a large amount of energy

9.  There is no away (conservation of matter)  You cannot get something for nothing (1 st law)  You cannot break even (2 nd law) Three Scientific Laws

15. Little Boy - Uranium It exploded with an energy of 16 kilotons of TNT (67 TJ). It has been estimated that 130,000 to 150,000 people had died as a result of its use by the end of December 1945 kilotons of TNT

16. Hiroshima  The mushroom cloud over Hiroshima after the dropping of "Little Boy"mushroom cloudHiroshima

18. Fat Man - Plutonium It exploded with an impact of 21 kilotons of energy (75 million sticks of dynamite) An estimated 39,000 people were killed outright by the bombing at Nagasaki, and a further 25,000 were injured. Thousands more died later from related blast and burn injuries, and hundreds more from radiation illnesses from exposure to the bomb's initial radiation.

19. Nagasaki  Mushroom cloud from the atomic explosion over Nagasaki rising 60,000 feet into the air on the morning of August 9, 1945.
