QUES: 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?

MY QUESTION: Is an arrow released from a bow an example of mechanical energy?

QUES: After becoming disabled in a machete attack on a visit to his native Haiti, Jean-Claude Joseph needed help persuading his landlord to move him from a fifth-floor apartment to one on the ground floor. Isaac Benjamin became ensnared in a bureaucratic snafu that took away his Social Security disability payments for more than two years. The story of Martha, a woman from Sierra Leone, was more compelling. Beaten, raped and tortured in her politically repressive homeland, she knowingly used someone else's passport to escape to America, but was caught by immigration authorities upon her arrival. She desperately sought political asylum. Not the kind of cases that lead to ground-breaking upheavals in the law, but the kind of cases that are handled day in and day out by lawyers for the legally disenfranchised who have no where else to turn. The work of attorneys from Legal Services of New Jersey will be highlighted in a onehour documentary, "Quest for Justice," to be aired 9 p.m. today on New Jersey Network. Produced by NYD2, a communications firm based in Somerset, the documentary features case histories of clients whose needs ranged from housing to fighting off deportation. Joseph, a 54-year-old naturalized citizen, turned to Legal Services when the landlord of his federally subsidized apartment complex in Elizabeth turned a deaf ear to his request for a ground-floor apartment. Having lost the use of his left arm in warding off the machete attack during a robbery attempt, Joseph said he found it increasingly difficult to negotiate the five flights of stairs lugging groceries or laundry on the frequent occasions when the building's elevator was out of order. "With this, it became impossible for me to stay upstairs," he said, pointing to the scars on his forearm. "If I cannot carry my groceries or my laundry, how can I live?" "It was a compelling case," said Legal Services attorney Stephen St. Hilaire. "The key for us -- and we have to make tough decisions all the time on whether to take a case -- was visualizing what he had to do to get to the fifth floor, struggling with a bag of groceries," he said. Benjamin, 53, of Jersey City had been collecting Social Security disability after undergoing double bypass surgery when the checks stopped coming. He said the agency claimed he had failed to return a form updating the condition of his health. "But what got me was they didn't let me know they didn't get it, they just cut me off," he said, adding he found it impossible to negotiate the Social Security bureaucracy himself.

QUES: When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.
