How to Master Newton's first law of motion with NASA

Demystify Newton's first law of motion with none other than NASA -- the National Aeronautics and Space Administration. The United States government's most infamous agency and powerhouse of space exploration teaches you the law of inertia… Newton's first law of motion.

This NASA video segment from "Flight Testing Newton's Laws" 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.
