AI Thread Summary
The discussion focuses on the physics of pyrotechnics, specifically how to calculate the height and trajectory of aerial shells. Key factors affecting these calculations include the amount of propellant, maximum velocity, mortar dimensions, and forces such as drag and gravity. Participants seek formulas to integrate these variables for accurate predictions. A resource link to HyperPhysics is shared for further reference. Understanding these principles is essential for effective pyrotechnic design and safety.

Does anybody know any information reguarding the physics behind pyrotechnics?
Such as:
1. Figuring the height an aerial shell (projectile) will reach.
2. Graphing the path of the shell (projectile) when fired at an angle.

I understand what factors influence the answers to these questions, I just don't know how to put it all together.

Some factors that I know of would be:
1. The amount of propellent used to send the shell into the air.
2. The maximum velocity of the projectile.
3. The size(height, width) of the mortar from which it is fired.
4. Drag, Gravity, Weight, Speed etc..

Some formulas for figuring these out would be greatly appreciated.

Thanks.. Good page.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
