Question: Context: Assume that a school bus, like the one in Figure 12.2, passes by as you stand on the sidewalk. Its obvious to you that the bus is moving. It is moving relative to you and the trees across the street. But what about to the children inside the bus? They arent moving relative to each other. If they look only at the other children sitting near them, they will not appear to be moving. They may only be able to tell that the bus is moving by looking out the window and seeing you and the trees whizzing by. This example shows that how we perceive motion depends on our frame of reference. Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion. For the children on the bus, if they use other children riding the bus as their frame of reference, they do not appear to be moving. But if they use objects outside the bus as their frame of reference, they can tell they are moving. What is your frame of reference if you are standing on the sidewalk and see the bus go by? How can you tell the bus is moving? The video at the URL below illustrates other examples of how frame of reference is related to motion. MEDIA Click image to the left or use the URL below. URL: Did you ever go to a track meet like the one pictured in Figure 12.3? Running events in track include 100-meter sprints and 2000-meter races. Races are named for their distance. Distance is the length of the route between two points. The length of the route in a race is the distance between the starting and finishing lines. In a 100-meter sprint, for example, the distance is 100 meters. The SI unit for distance is the meter (1 m = 3.28 ft). Short distances may be measured in centimeters (1 cm = 0.01 m). Long distances may be measured in kilometers (1 km = 1000 m). For example, you might measure the distance a frogs tongue moves in centimeters and the distance a cheetah moves in kilometers. Maps can often be used to measure distance. Look at the map in Figure 12.4. Find Mias house and the school. You can use the map key to directly measure the distance between these two points. The distance is 2 kilometers. Measure it yourself to see if you agree. Things dont always move in straight lines like the route from Mias house to the school. Sometimes they change direction as they move. For example, the route from Mias house to the post office changes from west to north at the school (see Figure 12.4). To find the total distance of a route that changes direction, you must add up the distances traveled in each direction. From Mias house to the school, for example, the distance is 2 kilometers. From the school to the post office, the distance is 1 kilometer. Therefore, the total distance from Mias house to the post office is 3 kilometers. You Try It! Problem: What is the distance from the post office to the park in Figure 12.4? Direction is just as important as distance in describing motion. For example, if Mia told a friend how to reach the post office from her house, she couldnt just say, "go 3 kilometers." The friend might end up at the park instead of the post office. Mia would have to be more specific. She could say, "go west for 2 kilometers and then go north for 1 kilometer." When both distance and direction are considered, motion is a vector. A vector is a quantity that includes both size and direction. A vector is represented by an arrow. The length of the arrow represents distance. The way the arrow points shows direction. The red arrows in Figure 12.4 are vectors for Mias route to the school and post office.

Question: Context: The week 3 matchup vs. the Texans proved to be a greater challenge for the Patriots than the Saints had been in week 2. The Patriots scored first on a 7-play drive ending with a Tom Brady 5-yard throw to Rob Gronkowski, who was playing with a groin injury that took him out of the previous week's game. The game would progress through seven lead changes, as Texans rookie quarterback DeShaun Watson would go drive-for-drive against Brady. Watson threw two touchdowns, one of which to his tight end Ryan Griffin, who attended college in New England at Connecticut. Two field goals late in the game would give the Texans their final lead at 33-28. With less than 2:25 remaining in the game, Brady led the Patriots on a frantic 8-play 71-yard drive that culminated in a 25-yard reception by Brandin Cooks to give the Patriots the 36-33 win. 
 Question: Who did the Patriots beat before beating the Texans?

Answer: saints


Question: Context: The film begins some years in the future from this exact moment. We see ads everywhere (buildings, walls, bus stops, e.t.c) for the hit game Slayers, and how the star character Kable (Gerard Butler) has four battles left before he earns his freedom. We are then shown a battle in progress: a massive shootout inside a factory. Everyone in the game is controlled by players elsewhere. Characters get points for each kill and for saving a teammate. Some characters are shown to be doing menial tasks in the battlefield, seemingly unaware of all the violence around them. 17-year-old Simon (Logan Lerman) plays/controls Kable and leads him around the factory. After slaughtering most everyone in his way, Kable gets blasted outside of the factory. Kable manages to run to the safe point to win the battle. Afterward, the surviving characters are transported elsewhere. The other characters congratulate Kable on winning, since he now only has three battles left until freedom. Some of the other characters don't believe that anyone will be released from the game.The producer (Michael Weston) and Chief of Staff, Bob, (John de Lancie) for the Gina Parker Smith Show discuss their next guest for the show - genius recluse Ken Castle, the creator of Slayers. On the show, Gina (Kyra Sedgwick) talks about the achievements of Ken Castle (Michael C. Hall). He first created a game called Society, which is basically a Sims game but instead of controlling a fake character, the players control a real person and can make them do whatever they want. You can pay to control someone else, or you can get paid to be controlled. Society quickly became extremely popular and profitable, making Castle the richest person in the universe. Nine months ago Castle created Slayers, a controversial game which is supported by the federal government. Castle defends Slayers by stating that each character in the game, though they are real people, are all death row inmates who chose to sign up for the game instead of doing their prison sentence. If a convict can stay alive for thirty battles, they will be set free (though no one has ever survived that long). Some convicts are sent into battlefields with pre-engineered actions to do, and will be set free if they survive just one battle, but are unable to defend themselves (which makes their death rate extremely high). Also, the games are all televised on pay-per-view. Everyone in Slayers and Society has had nano-cells implanted into their brains, which makes it possible for them to be controlled by someone else. They can only be controlled in the perimeter of the game (meaning after the game is over, they get their control back).After the show is over, the signal is hacked into by Humanz, a resistance group. The Humanz Brother (Ludacris) condemns Castle and states that eventually we will all be his slaves if we continue down this road. Castle gets a kick out of it and has his men try to locate where the signal came from. In prison, a convict beats a guard to death and tries to escape but in the end, he fails. Kable sits by himself and thinks about his family. Freek (John Leguizamo) sits next to Kable. He talks about how Kable spooks everyone else when he sits by himself and is constantly thinking. He can't believe that Kable only has three battles left. Freek asks him why he's in prison. Kable has a quick flashback of a man bleeding in a room. Later on, while sitting in his cell, someone opens the slot of the door and hands Kable a picture of his wife and child. The female voice on the other side knows that his family is the only thing he fights for. She makes Kable sign an autograph for her son, David, and then takes a blood sample from his hand as proof of authenticity to increase the value of the autograph.Elsewhere, we see Kable's wife Angie (Amber Valletta) going to work as a character in Society. Practically all the game characters are dressed in ridiculous and skimpy costumes
