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.

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.

Paul put the despised watch away And laid out before him his array Of stones and metals, and when the morning Struck the stones to their best adorning, He chose the brightest, and this new watch Was so light and thin it seemed to catch The sunlight's nothingness, and its gleam. Topazes ran in a foamy stream Over the cover, the hands were studded With garnets, and seemed red roses, budded. The face was of crystal, and engraved Upon it the figures flashed and waved With zircons, and beryls, and amethysts. It took a week to make, and his trysts At night with the Shadow were his alone. Paul swore not to speak till his task was done. The night that the jewel was worthy to give. Paul watched the long hours of daylight live To the faintest streak; then lit his light, And sharp against the wall's pure white The outline of the Shadow started Into form. His burning-hearted Words so long imprisoned swelled To tumbling speech. Like one compelled, He told the lady all his love, And holding out the watch above His head, he knelt, imploring some Littlest sign. The Shadow was dumb.

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.
