Physical science final exam review

  1. 1. Physical Science Final Exam REVIEW NAME: ____________________________ CLASS:_________ The following Physical Science competencies included in this exam packet: 1. Understand and apply concepts of the scientific method, introductory mathematical modeling, the use of scientific equipment, and scientific reporting in solving basic physics and chemistry problems. 2. Model, apply concepts, and solve problems related to the motion of objects and underlying forces. 3. Demonstrate, apply concepts, and solve problems related to the properties of light and sound waves. 4. Show the relationships between electricity and magnetism, apply those concepts and describe their roles in technology. 5. Make use of thermodynamic principles to show how matter and energy change within a system. 6. Show how the evolution of the atomic model explains the structure of the periodic table, the nature of atoms and make use of the periodic table to examine properties of elements. 7. Demonstrate their understanding of nuclear radiation, atomic energy, and the evolution of the universe. 8. Illustrate, apply concepts, and solve problems related to molecular bonding and chemical reactions. 9. Describe, apply concepts, and solve problems related to acids, bases, and carbon-based chemistry.
  2. 2. From Competency 1: 1. What are some of the most important lab safety points? 2. What are the basic units of length, mass, area, volume, energy, and density? 3.

How do you measure inertia and momentum? Give examples of items with different momentum and inertia.
  5. 5. 16. Compare and contrast the potential and kinetic energy of a snowboarder at the top, middle, and bottom of a ski hill. 17. What is driving that snowboarder down the hill? If he goes off a cliff, what is her acceleration? 18. Define work. If you held a bowling ball over your head very still for one hour without a break, how much work have you done on the ball? Explain!! From Competency 3: 19. Draw a transverse wave with an amplitude of three and wavelength of 8. Label the wave’s amplitude, crest, and trough. Show three places where you can find its wavelength. What is its wavelength? If the window above was a one second image of the wave, what is it’s frequency? Label it properly!
  6. 6. 20. What kind of energy does the wave in #19 carry? Are there other types of waves? Compare and contrast them! 21. What is the #1 job of ALL waves? 22. What is the Doppler effect, where do you hear it, and what is it? 23. Compare the speeds of light and sound. 24. List the types of energy found in the electromagnetic spectrum from low to high energy. 25. List the types of energy found in the electromagnetic spectrum from short waves to long waves. 26. Can you see through something opaque? How about transparent or translucent? Give examples. 27. What colors REALLY make up your cell phone display? 28. Why is the sky blue?
  7. 7. 29. Give an example of how the law of reflection works. 30. Why do glasses help someone see? What is that “bending light” thing called and why does it happen? 31. What are the different lens shapes and what are they commonly found? From Competency 4: 32. Define AC, DC, and Static electricity. Give an example of where you would find each type. 33. What are the voltage and frequency of the American power system? 34. Define volts, amps, resistance and watts. What are their proper units. 35. If you have ten strings of Christmas lights on your tree, and each string uses 120 V and 75 W, will you blow out the room’s 15 A circuit breaker? Prove it. 36. Describe the area both around a magnet and at the “ends” of a magnet. What are the proper names for this area?
  8. 8. 37. Draw a series circuit with a switch, battery and three light bulbs. Describe what would happen to the other lights if you were to pull out one of the lights from the string. Where might you find this type of circuit? Are there other kinds of circuits? How are they different? From Competency 5 38. Define heat, temperature, and thermal energy. 39.
