"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. (04:12)

Joe Biden, born on November 20, 1942, briefly worked as an attorney before turning to politics. He became the fifth-youngest U.S. senator in history as well as Delaware's longest-serving senator. His 2008 presidential campaign never gained momentum, but Democratic nominee Barack Obama later selected him as his running mate. When Obama was elected, Biden became the 47th vice president of the United States. In this video clip, learn more about Vice President Joe Biden. (04:31)

Calculus based review of definite integrals, indefinite integrals, and derivatives as used in kinematics. Graphs of position, velocity, and acceleration as a function of time are compared using derivatives and integrals. Two of the uniformly accelerated motion (or kinematics) equations are derived using indefinite integrals.
For the calculus based AP Physics C mechanics exam.

Content Times:
0:11 Rearranging the acceleration equation to get change in velocity
1:41 Rearranging the velocity equation to get change in position
2:06 Comparing graphs of position, velocity, and acceleration as a function of time
3:28 Using the integral to solve for one of the uniformly accelerated motion equations
4:44 Using the integral to solve for a second uniformly accelerated motion equation
FYI: I do not teach integrals until we get to Work. By then the students who are taking calculus concurrently with AP Physics C Mechanics have had enough experience with derivatives that they only freak out a little bit when I teach them integrals.

It’s hard to beat the market and you shouldn’t try. But what about market anomalies?
One anomaly is the Momentum Effect—where past stock performance predicts future performance, at least a bit. As an example, portfolios with past winners tend to outperform the market in the medium term. Why is that? The market sometimes under-responds to changes in information. Thus, some stocks can lag, even if rationally, they shouldn’t. This is why picking past winners can generate some profit, though the profit’s usually small.
There are also other anomalies, like the Monday Effect, where stocks fall more on Mondays. Or, there’s the January Effect, which says that stocks surge higher in that month. There’s been some evidence for these effects, but these anomalies don’t last.
Despite its flaws, the market is still more rational than you. Don’t forget, you’re probably like most individual traders. You may become overconfident. You may not calculate probabilities that well. And if the market crashes, you’re likely to act more emotionally than you should—just like everyone else.
But don’t just take our word for it — even Warren Buffett agrees! Don’t try to beat the market. (04:05)
