(Test-Drive: Carbon Footprint Calculator) Some scientists believe that carbon emissions, especially from the burning of fossil fuels, contribute significantly to global warming and that this can be combatted if individuals take steps to limit their use of carbon-based fuels. Organizations and individuals are increasingly concerned about their “carbon footprints.” Websites such as Terra Pass

and Carbon Footprint

www.carbonfootprint.com/calculator.aspx

provide carbon footprint calculators. Test-drive these calculators to estimate your carbon footprint. Exercises in later chapters will ask you to program your own carbon footprint calculator. To prepare for this, use the web to research the formulas for calculating carbon footprints.

Use the following terms to create a concept map: fossil, ice cores, climate, polar climate, climatologist, steppe, temperature range, tropical climate, middle-latitude climate, and savanna.

Express the conservation of momentum principle. What can you say about the momentum of a body if the net force acting on it is zero?

You can test the viscosity of a liquid by dropping a steel sphere into it and measuring the speed at which it sinks. For viscous fluids, the sphere will rapidly reach a terminal speed. At this terminal speed, the net force on the sphere is A. Directed downward. B. Zero C. Directed upward.

Use the concepts of gross investment and net investment to distinguish between an economy that has a rising stock of capital and one that has a falling stock of capital. Explain: “Though net investment can be positive, negative, or zero, it is impossible for gross investment to be less than zero.”
