The last thing you do at
an airport is to get on the plane.
When the plane takes off it uses the Bernoulli principle to be
able to take
off. The plane must have more lift force than drag force to
take off. We can
also use Newton’s first law, when a plane is flying in the air
and we are
ignoring air resistance in our equations. We can say that as
we increase the thrust,
we accelerate the aircraft but the drag also increases as the
faster we go. If
the drag and the thrust are equal then the aircraft holds a
higher or lower airspeed.
