About This Lesson
This NASA video segment explores how Newton's Laws of Motion apply to the development and operation of airplanes. Viewers watch an instructor at NASA's National Test Pilot School as he describes and then demonstrates why seatbelts are an important force on pilots; what it means to pull 2, 4 and even 6 g in a jet; and how the thrust of a jet engine causes an aircraft to move forward. Formulas are presented onscreen along with the calculations discussed in the segment.
