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.

Question: "What kind of position would an object need to possess gravitational potential energy?"

OPTIONS:
- no
- yes

Answer: "The object would need to be in a raised up position; wherever an object has the potential to fall"

Response: yes

Recommendation: Congressional oversight for intelligence-and counterterrorism-is now dysfunctional. Congress should address this problem. We have considered various alternatives: A joint committee on the old model of the Joint Committee on Atomic Energy is one. A single committee in each house of Congress, combining authorizing and appropriating authorities, is another. The new committee or committees should conduct continuing studies of the activities of the intelligence agencies and report problems relating to the development and use of intelligence to all members of the House and Senate. We have already recommended that the total level of funding for intelligence be made public, and that the national intelligence program be appropriated to the National Intelligence Director, not to the secretary of defense. We also recommend that the intelligence committee should have a subcommittee specifically dedicated to oversight, freed from the consuming responsibility of working on the budget. The resolution creating the new intelligence committee structure should grant subpoena authority to the committee or committees. The majority party's representation on this committee should never exceed the minority's representation by more than one. Four of the members appointed to this committee or committees should be a member who also serves on each of the following additional committees: Armed Services, Judiciary, Foreign Affairs, and the Defense Appropriations subcommittee. In this way the other major congressional interests can be brought together in the new committee's work. Members should serve indefinitely on the intelligence committees, without set terms, thereby letting them accumulate expertise. The committees should be smaller-perhaps seven or nine members in each house-so that each member feels a greater sense of responsibility, and accountability, for the quality of the committee's work. The leaders of the Department of Homeland Security now appear before 88 committees and subcommittees of Congress. One expert witness (not a member of the administration) told us that this is perhaps the single largest obstacle impeding the department's successful development. The one attempt to consolidate such committee authority, the House Select Committee on Homeland Security, may be eliminated. The Senate does not have even this. Congress needs to establish for the Department of Homeland Security the kind of clear authority and responsibility that exist to enable the Justice Department to deal with crime and the Defense Department to deal with threats to national security.

Question: "What are some suggestions for requirements of the people in this new committee that is being proposed?"

Response: "The majority of the committee should never exceed the minority by more than one and four of the members on the committee should also serve in Armed Services, Judiciary, Foreign Affairs and the Defense Appropriations subcommittee"

Problem: Josie started planning her new garden in the winter. She chose flowers and vegetables that could grow in her area. She looked through the seed magazines. She ordered the tastiest kind of each vegetable and the prettiest kind of each flower. She talked to a friend about her plans. It seemed like the snow would never melt. But Josie didn't have to wait for spring to get started. Six weeks before the last frost, Josie planted seeds indoors. The tiny seedlings pushed up through the soil and began to grow. Finally spring arrived. Each day, Josie moved the seedlings outside for a few hours so they could get used to the cooler temperatures. Josie worked in her garden, digging the soil. She added a special growing mix from the garden store to make the soil better. When everything was ready, she removed the seedlings from their trays and planted them in her garden. The warm sun and rich soil helped her vegetables and flowers grow.

Question: "What kinds of things did Josie want to plant?"

Answer: "Flowers"

OPTIONS:
- no
- yes
Answer: yes

Question:
(CNN) -- A Christian evangelical group said Thursday that a Bible school -- backed by American evangelist Franklin Graham -- was destroyed in the latest bombing raid to hit South Kordofan, an oil-rich Sudanese province that borders the newly created independent country of South Sudan. At least eight bombs were dropped in the area Wednesday during the school's first day of classes, according to a statement by Samaritan's Purse, Graham's Christian humanitarian group, which supports the school. Two bombs landed inside the compound -- located in the region's Nuba Mountains -- destroying two Heiban Bible College buildings and igniting grass fires across the area, the group said in a statement No injuries were reported. "It was a miracle that no one was injured," the statement added. Graham, who has called on the international community to take out Sudan's air assets and establish a no-fly zone in the region, said in a statement Thursday that he blamed Sudan's air force for the strike. At least four churches have been destroyed since August, the group said. "We are deeply concerned for the welfare and lives of the people of South Kordofan and we condemn the bombing of churches and Christian facilities," added Graham, son of the famed Rev. Billy Graham. More than 78,000 people have fled South Kordofan and Blue Nile states since August of last year after an armed rebellion took root, the United Nations reported. The Sudanese government is thought to have responded to the rebellion by conducting sustained air raids with the use of Russian-made Antonov bombers, which have raised concerns over civilian casualties. Decades of civil war between the north and south, costing as many as 2 million lives, formally ended with a U.S.-brokered peace treaty in 2005. After reading the above, is "Aircraft" the correct answer to the question "What did the bombs destroy?"? OPTIONS:
- no
- yes

Answer:
no

You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Question: "How do clouds develop different regions of charges?"

OPTIONS:
- no
- yes

Answer: "Because of movement of air molecules, water drops, and ice particles"

Response:
yes
