Vectors -- The Science of NFL Football


It's September 2015 and a new football season is starting. It's a good time to go back to The Science of NFL Football.

Vectors

NBC's Lester Holt looks at the role vectors play every time an NFL quarterback throws a pass. With the help of former NFL quarterback Joey Harrington, NSF-funded scientists John Ziegert, a professor at Clemson University, and Rhonda Hughes, a professor at Bryn Mawr College, explain how to use vectors to calculate the speed and direction needed for a completed pass.

Original air date: March 15, 2011
