In White House Down John Cale presents a wide amount of physics. The one he shows most is Newton's First Law. He is always on the move in the movie because if he were to stop he would get shot. He is also dodging bullets and fighting. Some parts where he demonstrates Newton's First Law is Running throughout the White House to start it on fire. Or when he is running through the tunnels trying to get the president to safety. Another one would be him fighting on top of the roof. So you can see that John Cale expressed this law very well in the movie.
