♠ HEllo!! ♠

Three things make a jet engine more powerful than a car's piston engine: ... A jet engine is meticulously designed to hoover up huge amounts of air and burn it with vast amounts of fuel (roughly in the ratio 50 parts air to one part fuel), so the main reason why it makes more power is because it can burn more fuel.

HOPE it helps to you!!

Explanation:

They essentially benefit from Newton's Second and Third Laws and the law of Conservation of Energy to put it in simplistic terms.

They accelerate mass and propell it at high velocities and in doing so, they experience an equal and opposite force which we term Thrust.

If we were to delve more deeply into it, we would have to look at the Thermodynamics as well, ie. How packing as much air into the combustor at the right mixture composition with fuel, which when ignited, leads to the creation of gasses which are subsequently expelled at high velocities through a turbine, the rotational power from which is used to drive a compressor ahead of the combustor, allowing for as much air to be 'packed' into the combustor as previously mentioned.

I'll leave it to the Thermodynamicsts and Fluid mechanics specialists to get into the details and provide a much more accurate and insightful explanation.

I might add that modern jet engines now use that turbine generated power - through the use of large fans - to propel bypass Air (Air which does not enter the compressor section of the engine) at high velocities (less than that of the exhaust from the turbine) and thus make use of Newton's Second and Third Laws to develop what we refer to as Thrust.
