Nahh, I don't think so. one object at 100MPH, another object at 10,100MPH, where deltaV is 10,000. Applying the deltaT to the field around the object wouldn't make that 100mph object go to 10,000mph. That's not what makes rockets go so fast. It's PV=nRT. PV/nR =T deltaPV/nR =delta T, which is

[Vo]:Direct flow acceleration

Imagine a flying object, maybe a sphere or cylinder for simplicity, the gas flowing around the object has to flow around it, the gas is forced to move around the object. Such forces need to have a pressure gradient force ( volumetric force = ∇ pressure) , and the pressure change corresponds to a te
