Problem: We need natural resources for just about everything we do. We need them for food and clothing, for building materials and energy. We even need them to have fun. Table 2.1 gives examples of how we use natural resources. Can you think of other ways we use natural resources? Use Vehicles Resources Rubber for tires from rubber trees Steel frames and other metal parts from minerals such as iron Example iron ore Electronics Plastic cases from petroleum prod- ucts Glass screens from minerals such as lead lead ore Use Homes Resources Nails from minerals such as iron Timber from trees Example spruce timber Jewelry Gemstones such as diamonds Minerals such as silver silver ore Food Sunlight, water, and soil Minerals such as phosphorus corn seeds in soil Clothing Wool from sheep Cotton from cotton plants cotton plants Recreation Water for boating and swimming Forests for hiking and camping pine forest Some natural resources are renewable. Others are not. It depends, in part, on how we use them.

Question: "What are some basic reasons we need natural resources?"

Answer: "Strong economy"

Problem: MALS was formed here more than 30 years ago. Today, 14 staff attorneys, 26 office workers and 21 University of Memphis third- year law students work out of rented offices in the old Claridge Hotel building at 109 N. Main. Offices are spartan. There are no lush rugs or stylish furniture. The large table in the conference room is simple varnished wood. Offices are small and mostly plain, except for the eclectic mix of pop art, African statuary and neon that adorns litigation director Webb Brewer's space. Brewer, who has been at the agency 20 years, said there is a need for lawyers of all stripes to help with the problems of the poor. "The private bar could meet more of the need through pro bono work, but there are still cases that involve the systemic problems for low-income people that we would need to do," said Brewer. "The legal system marketplace just doesn't serve low-income people too well, except in fee-generat-ing type cases," Brewer said. "If a poor person gets run over by a bus, an attorney might take that case because they might be able to recover part of the damage award as attorney fees. But so many of the cases we handle have to do with basic rights and a decent life. There is just no profit motive." Larry Pivnick, law professor at the University of Memphis Law School and director of political programs at MALS, said Legal Services is a great learning laboratory for law students. "There are thousands and thousands of people who have problems that never get an opportunity to appear in court," Pivnick said. "Some people may not be particularly articulate. Courts have rules that clients don't always understand." Brewer said a major focus of the agency's work involves housing. "Although a lot of our work is grant-driven, we find that the lack of safe and decent affordable housing and the prevalence of predatory lending are the biggest problems in our client population," Brewer said, referring to clients such as James.

Problem: Gravitational Potential Energy is affected by position. Like the leaves on trees, anything that is raised up has the potential to fall. It has potential energy. You can see examples of people with gravitational potential energy in 1.5 Figure below. Gravitational potential energy depends on two things. It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree. It also depends on its height above the ground. Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom. Like all energy, gravitational potential energy has the ability to do work. In this case, weight has the potential to deliver a force. More important for us is that it has the ability to cause change. What kind of change you may ask? Gravitational potential energy has the ability to cause motion.

Question: "What are two things that effect the force of the fall?"

Answer: "Kinetic Energy"

OPTIONS:
- no
