QUES: Gravitational Potential Energy is affected by position. Like the leaves on trees, anything that is raised up has the potential to fall. It has potential energy. You can see examples of people with gravitational potential energy in 1.5 Figure below. Gravitational potential energy depends on two things. It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree. It also depends on its height above the ground. Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom. Like all energy, gravitational potential energy has the ability to do work. In this case, weight has the potential to deliver a force. More important for us is that it has the ability to cause change. What kind of change you may ask? Gravitational potential energy has the ability to cause motion.

MY QUESTION: Name two examples of the effect of gravitational potential energy that are given in the paragraph.

QUES: The hijackers attacked at 9:28. While traveling 35,000 feet above eastern Ohio, United 93 suddenly dropped 700 feet. Eleven seconds into the descent, the FAA's air traffic control center in Cleveland received the first of two radio transmissions from the aircraft. During the first broadcast, the captain or first officer could be heard declaring "Mayday" amid the sounds of a physical struggle in the cockpit. The second radio transmission, 35 seconds later, indicated that the fight was continuing. The captain or first officer could be heard shouting:" Hey get out of here-get out of here-get out of here." On the morning of 9/11, there were only 37 passengers on United 93-33 in addition to the 4 hijackers. This was below the norm for Tuesday mornings during the summer of 2001. But there is no evidence that the hijackers manipulated passenger levels or purchased additional seats to facilitate their operation. The terrorists who hijacked three other commercial flights on 9/11 operated in five-man teams. They initiated their cockpit takeover within 30 minutes of takeoff. On Flight 93, however, the takeover took place 46 minutes after takeoff and there were only four hijackers. The operative likely intended to round out the team for this flight, Mohamed al Kahtani, had been refused entry by a suspicious immigration inspector at Florida's Orlando International Airport in August. Because several passengers on United 93 described three hijackers on the plane, not four, some have wondered whether one of the hijackers had been able to use the cockpit jump seat from the outset of the flight. FAA rules allow use of this seat by documented and approved individuals, usually air carrier or FAA personnel. We have found no evidence indicating that one of the hijackers, or anyone else, sat there on this flight. All the hijackers had assigned seats in first class, and they seem to have used them. We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.

MY QUESTION: How many hijackers sat in first class?

QUES: Mr. Thorndike had risen, and, in farewell, was holding out his hand to Andrews. He turned, and across the court-room the eyes of the financier and the stenographer met. At the sight of the great man, Spear flushed crimson, and then his look of despair slowly disappeared; and into his eyes there came incredulously hope and gratitude. He turned his head suddenly to the wall. Mr. Thorndike stood irresolute, and then sank back into his chair. The first man in the line was already at the railing, and the questions put to him by the judge were being repeated to him by the other assistant district attorney and a court attendant. His muttered answers were in turn repeated to the judge. "Says he's married, naturalized citizen, Lutheran Church, die- cutter by profession." The probation officer, her hands filled with papers, bustled forward and whispered. "Mrs. Austin says," continued the district attorney, "she's looked into this case, and asks to have the man turned over to her. He has a wife and three children; has supported them for five years." "Is the wife in court?" the judge said. A thin, washed-out, pretty woman stood up, and clasped her hands in front of her. "Has this man been a good husband to you, madam?" asked the young judge. The woman broke into vehement assurances. No man could have been a better husband. Would she take him back? Indeed she would take him back. She held out her hands as though she would physically drag her husband from the pillory. The judge bowed toward the probation officer, and she beckoned the prisoner to her.
