Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel....

portion of the unit. A rocket stove can be used as a heat or a cooking source and is often included as part of the setup in outdoor campsites. Because a rocket stove requires less fuel than an opencampfire, it can be ideal for preparing all types of food while enjoying the outdoors...
The rocket is made of stainless steel, a material Musk is particularly fond of due to its relatively low price. Unlike NASA's SLS, which flies on super-chilledliquid hydrogen and oxygen, this beast is fueled with 10 million pounds of liquid methane and oxygen. The new fuel can be stored...
So we are burning up an enormous amount of fuel at every launch, just to get the rocket up to what's known as "escape velocity". Now, escape velocity is around 11 kilometers a second, pretty fast. But do we really have to go this fast?FEMALE STUDENT: Well...yeah! I mean, how ...
