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?

Responding to a wave of public dismay over the first designs for rebuilding Lower Manhattan, Gov. George Pataki has sent word that it's time to go back to the drawing board. It is the right message, sent while it is still early enough to do something constructive about the disappointing quality of the work so far. The governor, like Mayor Michael Bloomberg, now seems committed to creating a better mix of uses for ground zero, and a 24-hour community in Manhattan's downtown. While rethinking the plans will delay the original rebuilding schedule slightly, it does not need to stall progress if the governor keeps the pressure on the Lower Manhattan Development Corp. and the Port Authority of New York and New Jersey. New York cannot afford to have a gaping hole that mocks the city and its process for rebuilding what was destroyed. Pataki openly questioned the Port Authority's requirement that any plan for the site replace all the office, hotel and retail square footage lost in the attack on Sept. 11. More than anything else, that specification limited the designs to the undistinguished options presented two weeks ago. Renegotiating that issue with the World Trade Center leaseholders should begin immediately. Opening the process to other designers, both here and internationally, will help separate this urban plan from the ordinary. The city also needs to begin openly discussing what happens underground, in particular with the transportation network. At this point, planners have focused on short-term repair of PATH and subway lines, with medium-range proposals being shopped in Washington that could untangle the disorganized web of subway lines downtown. Within the next few weeks the Lower Manhattan Development Corp. and the Port Authority should offer some bigger ideas about how to connect the downtown area better to the rest of the region. Lowering West Street alongside the World Trade Center site and building a park or esplanade on top is another option that has been popular with those reviewing the first six public proposals. But it would be expensive, and the governor, the mayor and their friends in Washington will have to look at long-range ways to pay the bill. Pataki's recent remarks are a sign that he understands how central the rebuilding of Lower Manhattan will be to his own political legacy. Now he needs to follow through with action, to keep demonstrating that his core concern is coming up with the best possible plan, not simply keeping the issue on hold until after this fall's election.

Problem: Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged.

Question: "What causes objects to attract or repel each other?"

Answer: "Objects"

If you beat a dog in Schuylkill County, you'll probably get a $100 fine. If you repeatedly beat a woman, you'll probably get the same fine. In 2001, county judges heard 98 Protection From Abuse cases, finding the defendant guilty in 48 percent of those cases, either after a hearing or through a technical violation or plea. Of those found guilty, the majority were ordered to pay court costs, plus a $100 fine. No defendants were ordered to pay more than a $250 fine for violating the court order. In 27 percent of the cases, the charges were dismissed or the defendant was found not guilty. In the rest of the cases, charges were withdrawn or the matter is not yet resolved. Sarah T. Casey, executive director of Schuylkill Women in Crisis, finds it disturbing that in most cases, the fine for violating a PFA is little more than the fine someone would get for cruelty and abuse toward an animal. "In most of the counties surrounding Schuylkill County, the penalties given for indirect criminal contempt are much stiffer than those in Schuylkill County," Casey said. "What kind of message are we sending those who repeatedly violate Protection From Abuse orders? That it's OK to abuse women in Schuylkill County, because you'll only get a slap on the wrist?" Under state law, the minimum fine for contempt of a PFA is $100; the maximum fine is $1,000 and up to six months in jail. Like others who are familiar with how the county's legal system does and doesn't work for victims of domestic violence, Casey believes some changes are in order. Valerie West, a manager/attorney with Mid-Penn Legal Services, with offices in Pottsville and Reading, regularly handles domestic violence cases. She finds fault with the local requirement that a custody order must be established within 30 days after a PFA is filed. West said she feels a custody order should be allowed to stand for the full term of the PFA - up to 18 months - as it does in many other counties in the state. "It places an undue burden on the plaintiff, in terms of cost, finding legal representation and facing their abuser - not to mention a further burden on the system to provide those services," West said. "It may be difficult for the parties to reach an agreement so soon after violence has occurred.
