"Science of NFL Football" is a 10-part video series funded by the National Science Foundation and produced in partnership with the National Football League. In this segment, NBC's Lester Holt breaks down Isaac Newton's First Law of Motion and how it can change how fast players can speed the football up or slow it down. Professors Tony Schmitz of the University of Florida and Jim Gates of the University of Maryland explain why the control of inertia is so vital to the outcome of the game.
