Thrust ⏬⏬

The force acting on a surface in a direction perpendicular to the surface.

Answer 2

Thrust is a force or a push. When a system pushes or accelerates mass in one direction, there is a thrust (force) just as large in the opposite direction. In math and physics, this is described by Isaac Newton’s second and third laws. Thrust is used to describe how strongly an engine pushes. It can be used for many kinds of vehicles and engines such as rockets, motorboats, propellers, and jet engines.

Thrust is measured in “pounds of thrust” in the U.S. and in Newtons in the metric system. 4.45 Newtons of thrust equals 1 pound of thrust. A pound of thrust is how much thrust it would take to keep a one pound object unmoving against the force of gravity on earth.

Thrust compared to power

Edit

A very common question is how to compare the thrust number of an airplane engine with the mechanical power of a piston engine (the kind of engine in cars and in many airplanes with propellers). It is hard to compare these two. This is because they are not measuring the same exact thing. A piston engine does not move the plane. It just turns the propeller, which moves the plane. Because of this, piston engines are rated by how much power they give to the propeller.

However, a jet engine has no propeller – it pushes the aircraft by moving hot air behind it. A useful way to measure the power of a jet engine is to how much power the jet engine gives to the aircraft through its thrust force. This is called the “propulsive power of the jet engine”. Power is how much force it takes to move something over a distance, divided by the time it takes to move that distance:[1]

{\displaystyle \mathbf {P} =\mathbf {F} {\frac {d}{t}}} {\displaystyle \mathbf {P} =\mathbf {F} {\frac {d}{t}}},

Where P is power, F is force, d is distance, and t is time. For a rocket or jet engine, the force is the same as thrust produced by the engine. Distance divided by time is also called speed. So power is the same as thrust times speed[2]

{\displaystyle \mathbf {P} =\mathbf {T} {v}} {\displaystyle \mathbf {P} =\mathbf {T} {v}},

Where T is thrust and v is speed. This is the power being delivered by the engine at a certain thrust or velocity.[3] The propulsive power of a jet engine increases with its speed
