"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 Third Law of Motion and how energy transfers between football players who collide during a game. Professors Tony Schmitz of the University of Florida and Jim Gates of the University of Maryland explain why momentum can keep a player moving or stop them in their tracks.
