A Jet Engine!

A jet engines power the fastest cars in the world as well as high-speed aircraft. A jet engine sucks in air at the front and heats this air with burning fuel. It then sends the hot air blasting out from the back of the engine. this forces the aircraft or car forward at very high speeds.



How a Jet Engine Works
All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The compressor is made up of fans with many blades and attached to a shaft. The blades compress the air. The compressed air is then sprayed with fuel and an electric spark lights the mixture. The burning gases expand and blast out through the nozzle, at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward.

Newton's laws of motion are three physical laws that form the basis for classical mechanics. They have been expressed in several different ways over nearly three centuries,[1] and can be summarised as follows:

1.In the absence of a net force, a body either is at rest or moves in a straight line with constant speed.
2.A body experiencing a force F experiences an acceleration a related to F by F = ma, where m is the mass of the body. Alternatively, force is equal to the time derivative of momentum.
3.Whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction.
