When a jet engine expels hot gases rearward at high speed, the reaction force pushes the aircraft forward. Jets can be found in nature, such as the powerful ejections from cephalopods or the high-speed streams from volcanic vents, but the term is most commonly associated with engineered systems like aircraft engines and industrial machinery.

Atmospheric Jets: These function within the Earth's atmosphere and include turbojets, turbofans, and ramjets. Reaction and Newton’s Laws Jet propulsion is a direct application of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
In medicine, laparoscopic jets facilitate minimally invasive surgery, and in manufacturing, jets are used for cleaning surfaces or drying products. Fundamental Principles of Jet Propulsion The core mechanism behind any jet system is the conversion of stored energy into kinetic motion.

Engineering and Design Considerations The design of a jet system involves complex trade-offs between efficiency, power, weight, and cost. Classification of Jets Jets are categorized primarily by the medium they operate in and the technology used to generate thrust.
