Assignment: "The Physics of Superheroes"& Energy
Chapter 11: "The Central City Diet Plan-Conservation of Energy"
Answer each question in detail as you read....do not copy the book. Put the answers in your own words and try to understand the material. Be concise and succinct.
A. What exactly does food contain that is essential for any activity, whether running, walking, or even sittingstill? And why do we only obtain these qualities from organicmatter, and not from rocks or metal or plastic?
B. How does the Sun provide energy? How is this energy used by humans here on Earth....93 million miles away from the Sun?
C. What is Energy? How are Potential and Kinetic Energy related?
D. Explain how Gwen Stacy's fall demonstrates the relationship between Kinetic and Potential Energy.
E. When Spiderman swings on his web....
1. What is the force acting on him (mass) to cause all of his motion(acceleration)?
2. Where is his "moment of inertia" ? (the place where the energy/force has to overcome his inertia)
3. How does Spiderman swinging relate to Potential & Kinetic Energy?
4. How does this example demonstrate Newton's laws of Motion?
5. Why can Spiderman never reach a point higher than his starting point each time he swings? How is the First Law of Thermodynamics demonstrated by a person swinging on a swing?...or Spiderman swing on his web?
F. What did Pauli suggest happened to the "missing" energy in radioactive decay reactions? Why was this important in terms of the Law of Conservation of Energy being "right" or "wrong"? What are "Ghost Particles"?
G. What is the most prevalent form of matter in the universe?
H. LIST step-by-step how the energy in gasoline is turned into the kinetic energy of the automobile. Pay attention to the energy changes. Why are heat and sound called "wasted energies"?
I. Explain how the First Law of Thermodynamics (law of conservation of energy) is demonstrated by the Flash coming to a stop after running at 500 mph. How many NEWTONS of force would this require to stop him? What do you think would happen to the earth under his feet...or even to his shoes? Why? (Think back to your answer to 6 & 7)
J. How does Kinetic Energy relate to heat calories and to Calories in food?
K. What is the reason that 1 kg-meter2/sec2is equal to this odd number of calories (0.24, to be exact)? How was James Prescott Joule involved in this? Support your answer with the information in the reading.
