Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

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.

Dick was enraged to see how contentedly the men bore the irksome confinement, the meager food, and harsh peremptoriness of the beardless boys set over them as guards. Most of the prisoners passed the time in cards, playing for buttons, trinkets, or what not that formed their scanty possessions. Dick learned that all the commissioned officers of the company with Wesley Boone had been wounded or killed in the charge near the stone bridge. Wesley had been with the prisoners at first. He had been struck on the head, and was in a raging fever when his father and sister came to the prison to take him away. No one could tell where he was now, but Dick knew that he must be in the city, since there were no exchanges, the Confederates allowing no one to leave the lines except women with the dead, or those who came from the North on special permits. Then he visited the provost headquarters, and was shown the complete list of names recorded in the books there; but Barney's was not among them. At the Spottswood Hotel, the day after his coming, he met Elisha Boone, haggard, depressed, almost despairing. Dick had no love for the hard-headed plutocrat, but he couldn't resist making himself known.

For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference?
