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.

Answer: What affect does gravitational potential energy have on leaves?

Even after Bin Laden's departure from the area, CIA officers hoped he might return, seeing the camp as a magnet that could draw him for as long as it was still set up. The military maintained readiness for another strike opportunity. On March 7, 1999, Clarke called a UAE official to express his concerns about possible associations between Emirati officials and Bin Laden. Clarke later wrote in a memorandum of this conversation that the call had been approved at an interagency meeting and cleared with the CIA. When the former Bin Laden unit chief found out about Clarke's call, he questioned CIA officials, who denied having given such a clearance. Imagery confirmed that less than a week after Clarke's phone call the camp was hurriedly dismantled, and the site was deserted. CIA officers, including Deputy Director for Operations Pavitt, were irate." Mike" thought the dismantling of the camp erased a possible site for targeting Bin Laden. The United Arab Emirates was becoming both a valued counterterrorism ally of the United States and a persistent counterterrorism problem. From 1999 through early 2001, the United States, and President Clinton personally, pressed the UAE, one of the Taliban's only travel and financial outlets to the outside world, to break off its ties and enforce sanctions, especially those relating to flights to and from Afghanistan. These efforts achieved little before 9/11. In July 1999, UAE Minister of State for Foreign Affairs Hamdan bin Zayid threatened to break relations with the Taliban over Bin Laden. The Taliban did not take him seriously, however. Bin Zayid later told an American diplomat that the UAE valued its relations with the Taliban because the Afghan radicals offered a counterbalance to "Iranian dangers" in the region, but he also noted that the UAE did not want to upset the United States.

You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.

Answer:
Can oil reduce the amount of heat that is produced from the moving parts of a car?
