Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.

(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.

Simply put, energy is the ability to a cause change. Energy can cause many types of change. Think about when you have a lot of energy. You are able to do a lot of things. When you dont have a lot of energy, you may sit around and do very little. A similar thing happens to particles of matter as energy is added. The more energy there is, the faster the particles of matter move. Energy is also the reason you are able to move around. In fact, matter is always in motion. It can even change from one form to another. For example, electrical energy can be converted into heat energy. You see this every time you use the toaster. Energy causes a change in matter when you lift your arm. Energy can be used to move matter. You use energy to take a step to move forward. Thanks to energy, your body moves. The energy of moving matter is called kinetic energy.

The Mummy 's Shroud is set in 1920 and tells the story of a team of archaeologists who come across the lost tomb of the boy Pharaoh Kah-To-Bey . The story begins with a flash back sequence to Ancient Egypt and we see the story of how Prem , a manservant of Kah-To-Bey , spirited away the boy when his father was killed in a palace coup and took him into the desert for protection . Unfortunately , the boy dies and is buried . The story then moves forward to 1920 and shows the expedition led by scientist Sir Basil Walden and business man Stanley Preston finding the tomb . They ignore the dire warning issued to them by Hasmid , a local Bedouin about the consequences for those that violate the tombs of Ancient Egypt and remove the bodies and the sacred shroud . Sir Basil is bitten by a snake just after finding the tomb . He recovers , but has a relapse after arriving back in Cairo . Preston takes advantage of this and commits him to an insane asylum , to take credit for finding the tomb and Prince 's mummy himself . Meanwhile , after being placed in the Cairo Museum , the mummy of Prem is revived when Hasmid chants the sacred oath on the shroud . The mummy then proceeds to go on a murderous rampage to kill off the members of the expedition , beginning with Sir Basil after he escapes from the asylum . One by one , those who assisted in removing the contents of the tomb to Cairo are eliminated by such grisly means as strangulation , being thrown out of windows , and having photographic acid thrown in their face .
