Jet Engine in AP World History: Modern

Definition

A jet engine is a type of engine that propels an aircraft by expelling jet streams of hot gases, created by burning fuel with air, producing thrust based on Newton's third law of motion. This technological advancement revolutionized air travel, enabling faster, more efficient flights and changing the dynamics of global conflict by altering military strategies and logistics.
