This NASA video segment explores how Newton's first law of motion applies to aerospace. An instructor at NASA's National Test Pilot School defines the law of inertia and then explains how the seatbelt in a jet provides an outside force to stop the inertia of the pilot. The instructor also discusses inertia experienced by humans while riding in the test vehicles for space travel.
