Editing Jet force (section)

=== Thrust ===
To analyze thrust, we take a mathematical perspective.

# First, an aircraft takes off at some angle with respect to the ground. For a rocket traveling straight "up", this angle would be 90°, or at least close to 90°. For airplanes and most other aircraft, this angle will be much less, generally ranging from 0° to 60°. We shall define this angle as θ.
# θ is constantly changing as the aircraft moves around. At any given moment, however, the cosine of this angle θ will give us the component of the force that is acting in the forward direction. Multiplying the total force by this cosine of θ would yield the thrust: <math display="block">\text{Thrust} = \text{Jet Force} \times \cos\theta</math>

Because θ ranges from 0° to 90° and the cosine of any angle in this range is 0 ≤ cos&nbsp;θ≤ 1, the thrust will always be either less than or equal to the jet force- as expected, as the thrust is a component of the jet force.
