Been lurking on these threads looking for easy explanations of E=mc2 as it relates to nuclear fission weapons. Shame, SHAME, to yall advanced physicists who dismiss and disrespect and flame amateurs on other threads asking for easy examples for kids. I'm a humanities teacher teaching Astrophysics. I hate math and so do my kids. 1. Do you know of a kids science website that best explains E=MC2? 2. How can you easily explain E=MC2 without using math, so that a 10-year-old girl easily understands? All explanations I've seen merely review each factor without APPLYING real world examples like atomic bombs. 3. How does C2 apply to Hiroshima? "C2 refers to the tremendous amount of potential energy E hiding in every object." So Mass can be converted to Energy, in case of Fatman and Littleboy, by imploding TNT against Uranium to release an atomic chain reaction. How do nuclear bombs relate to lightspeed? 4. What is difference between 1kg of my body, 1kg baseball, 1kg uranium, 1kg plutonium? Does 1kg yield exact same amount of Energy whether it is a baseball or fistful of plutonium? 5. What am I missing? I can only think of Hiroshima for nuclear fission and our sun for nuclear fusion of hydrogen into helium. I cannot picture how nuclear power plants control rate of chain reactions. Nor can I picture how a rock can remain radioactive for thousands of years. 6. How does light APPLY to explosive release of potential energy? How do light photons produced by stars relate to C2 created by a nuclear power plant? Would E=MC2 be impossible if you remove photons from equation, or is C2 not sunlight but merely a proxy for potential energy and has nothing to do with light photons? 7. If C2 means the Potential Velocity of an object is lightspeed squared, how do you explain that to a kid? Velocity of a baseball or just one atom inside baseball? Why is velocity lightspeed? What if velocity is less than lightspeed? How can you apply such a crazy concept using examples, or explain C2 as it relates to Star Trek Warp Speed? 8. What are other easy examples a kid could picture? Can you explain using real applied examples instead of math?
