Tõukejõud
Tõukejõud, in English thrust, is a fundamental concept in physics describing the force that propels an object forward. It is generated by expelling mass in the opposite direction, creating a reaction force according to Newton's third law of motion. This principle is most famously applied in jet engines and rocket propulsion. In a jet engine, air is drawn in, compressed, mixed with fuel, and ignited. The resulting hot gases are expelled at high velocity from the rear of the engine, generating thrust. Similarly, rockets expel hot gas and propellant at high speeds, allowing them to overcome gravity and atmospheric resistance to travel into space.
The magnitude of thrust depends on the mass of the expelled material and the velocity at which
