Hello. I’m trying to understand the nature and amount of force generated in an explosion. Take, for example, the explosion that results from the complete annihilation of one gram of matter, releasing 8.9876E+13 Joules. Let’s say that the initial volume of the explosive material is one cubic centimeter, shaped into a sphere with an area of .2244 square meters. Working through the inverse square law I end up with an output of 4.0050E+14, and this is where I begin to get confused. I get that having an area measuring less than 1.0 means that my final energy value will be greater than my original energy value, but while this might be mathematically correct it doesn’t reflect what would happen in the real world (making an explosive smaller does not make it more powerful). I suspect I’m missing something fundamental here, but being neither a mathematician nor a scientist I’m not sure what it is. My second point of confusion has to do with something I came across when I was reading up on the inverse square law. In the description I found the following statement: "At large distances from the source (compared to the size of the source)…”. What I’m wondering is what constitutes a “large” distance compared to the source. Is it twice the size? Ten times? Thank you for any help you can give me.
