Context: As elderly people go about their day in Manhattan, Harry walks along a sidewalk with his tabby cat Tonto on a leash, quoting Shakespeare's "King Lear" as he goes. Harry stops in at a grocer, buys some good food for his cat, and jokes that his sexual days are over.Next Harry meets his old friend Jacob on a bench, and tells him that his apartment building is being torn down to build a parking lot. Jacob complains about capitalists, and reassures Harry that he could always move in with him.On the way home, a kid tries to steal Harry's groceries and knocks him down. Harry is helped up by Leroy, his building super.Harry gets into his apartment and talks to Tonto, lamenting that he's been mugged four times in the past year, and that the whole city is getting run down.Some time later, police show up to forcibly remove Harry and his furniture from the building. Harry continues to spout "King Lear" while his son Burt arrives to pick him up.Harry goes to live with Burt and his wife and two grown sons in the suburbs. His younger grandson, Norman, has taken a vow of silence, leading to obvious tension with his brother and parents. Harry later asks Norman for the books that explain his beliefs.Harry goes back to his familiar bench to talk with Jacob, and they both agree it's been a long time since either has been with a woman. Jacob reminisces about his first sexual encounter with a servant girl when he was 14.Harry invites Leroy to dinner at Burt's house, and he plays the piano while Leroy dances to the tune. Leroy later comments that he lives with his 90-year-old mother and can't find a new job, which leads Burt's wife to question why Harry is not getting help from his two other kids.Knowing that he is a burden to Burt, Harry goes to look for his own apartment, but finds that the place he wants will not take cats. He then tells Burt he is going to Chicago to visit Shirley, Burt's sister, but before he leaves he stops at a city morgue to identify the body of Jacob, who has died with no relatives. Harry cries after recalling Jacob's story of losing his virginity.Burt takes Harry to the airport, but Harry soon learns that he can't go through security with Tonto, so he takes a cab to get a bus. Along the route, Harry asks the bus driver to stop so that Tonto can relieve himself, whereupon the cat runs away across a cemetery. The bus driver leaves Harry behind with his luggage, and when Tonto returns, Harry scolds him.Harry walks to a used car lot and buys an old Chevy for $250. He then checks into a motel and calls Burt to tell him what has happened, realizing in the process that his driver's license expired in 1958.Harry drives west rather slowly, with Tonto on the dashboard, recalling how he wanted to drive across the country when he was younger, but his wife and kids came along. He remembers they had many good times though. He confesses to Tonto that he has a great fear of pain, and that when he dies he would like to go quickly rather than the slow way his wife Annie died.Harry picks up two young hitchhikers, one of whom soon gets another ride, while the other a girl named Ginger continues west with Harry. She claims she is 16, and is running away from home to a commune in Boulder.Harry and Ginger get a motel for the night, and after she comes out of the bathroom half-naked, Harry is prompted to recall the first girl he loved, Jessie, whom he has not seen in 50 years. Ginger suggests that they go to see her, even though it's out of their way, and they eventually find her in a nursing home.At first Harry thinks Jessie remembers him, but her thoughts are marked by senility; she calls him Alex yet remembers his wife Annie. Then she suddenly asks Harry to dance, which they do while Ginger looks on.Harry

Context: Work is defined differently in physics than in everyday language. In physics, work means the use of force to move an object. The teen who is playing tennis in Figure 16.1 is using force to move her tennis racket, so she is doing work. The teen who is studying isnt moving anything, so she is not doing work. Not all force that is used to move an object does work. For work to be done, the force must be applied in the same direction that the object moves. If a force is applied in a different direction than the object moves, no work is done. Figure 16.2 illustrates this point. The stick person applies an upward force on the box when raising it from the ground to chest height. Work is done because the force is applied in the same direction as the box is moving. However, as the stick person walks from left to right while holding the box at chest height, no more work is done by the persons arms holding the box up. Thats because the force supporting the box acts in a different direction than the box is moving. A small amount of work in the horizontal direction is performed when the person is accelerating during the first step of the walk across the room. But other than that, there is no work, because there is no net force acting on the box horizontally. Work is directly related to both the force applied to an object and the distance the object moves. It can be represented by the equation: Work = Force Distance This equation shows that the greater the force that is used to move an object or the farther the object is moved, the more work that is done. You can see a short video introduction to work as the product of force and distance at this link: . To see the effects of force and distance on work, compare the weight lifters in Figure 16.3. The two weight lifters on the left are lifting the same amount of weight, but the bottom weight lifter is lifting the weight a longer distance. Therefore, this weight lifter is doing more work. The two weight lifters on the bottom right are both lifting the weight the same distance, but the weight lifter on the left is lifting a heavier weight. Therefore, this weight lifter is doing more work. The equation for work given above can be used to calculate the amount of work that is done if force and distance are known. For example, assume that one of the weight lifters in Figure 16.2 lifts a weight of 400 newtons over his head to a height of 2.2 meters off the ground. The amount of work he does is: Work = 400 N 2.2 m = 880 N m Notice that the unit for work is the newton meter. This is the SI unit for work, also called the joule (J). One joule equals the amount of work that is done when 1 newton of force moves an object over a distance of 1 meter. Problem Solving Problem: Todd pushed a 500 N box 4 meters across the floor. How much work did he do? Solution: Use the equation Work = Force Distance. Work = 500 N 4 m = 2000 N m, or 2000 J You Try It! Problem: Lara lifted a 100 N box 1.5 meters above the floor. How much work did she do? Did you ever rake leaves, like the woman in Figure 16.4? It can take a long time to do all that work. But if you use an electric leaf blower, like the man in the figure, the job gets done much sooner. Both the leaf blower and the rake do the work of removing leaves from the yard, but the leaf blower has more power. Thats why it can do the same amount of work in less time. Power is a measure of the amount of work that can be done in a given amount of time. Power can be represented by the equation: Power = Work Time In this equation, work is measured in joules and time is measured in seconds, so power is expressed in joules per second (J/
