Force Equals Mass Times Acceleration: Newton’s Second Law

This NASA video segment explores how Newton’s second law of motion applies to aerospace. Viewers watch an instructor at NASA’s National Test Pilot School as he defines the second law and demonstrates how to calculate a person’s mass using the law. There is also a discussion about how people experience different g forces at the top and bottom of a roller coaster hill. Footage of the instructor in a fighter jet illustrates what it means to pull 2 and 4 g.
