We can derive the potential energy stored in an ideal spring when it is stretched or compressed by computing the work done due to Hooke’s law. In this experiment we will be working with springs. When they are not being stretched by some external force, the coils of these springs are held tightly together by the spring’s rigidity. They are held so tightly that a small amount of weight can be hung from these springs, and they don’t stretch at...

Learning Goal: To understand how to apply the law of conservation of energy to situations with and without nonconservative forces acting. The law of conservation of energy states the following: In an isolated system the total energy remains constant. If the objects within the system interact through gravitational and elastic forces only, then the total mechanical energy is conserved. The mechanical energy of a system is defined as the sum of kinetic energy K and potential energy U. For such...

The value of a share of common stock depends on the cash flows it is expected to provide, and those flows consist of the dividends the investor receives each year while holding the stock and the price the investor receives when the stock is sold. The final price includes the original price paid plus an expected capital gain. The actions of the marginal investor determine the equilibrium stock price. Market equilibrium occurs when the stock's price is -Select-less thanequal togreater...

Economic inequality is a huge issue. A recent study found that the world’s 80 wealthiest individuals own as much as the entire world’s poorest 3.5 billion people. The richest 1 percent of the world’s population control half of the world’s total wealth. Many individuals, corporations, charities, and government agencies have projects and programs in place to attempt to tackle this and other important global issues such as sustainability, but there are many opportunities to do more. A grassroots group of...
