1 Name DATE Per Completion Complete each statement. TEST REVIEW 1. The two most common systems of standardized units for expressing measurements are the system and the system. 2. A picture that shows how two variables are related is called a. 3. On a graph, the independent variable is represented on the axis. 4. The would be the most practical unit to use for expressing the time it takes to blink. 5. The metric system is easier to use because basic units are related to larger and smaller units by a factor of. 6. The dependent variable is generally plotted on the axis of a graph. 7. Arrows are used to represent vector quantities. The arrow head represents the while the arrow s length represents the. 8. Although we use many units for measuring time, for most of physical science we measure and record time in. 9. A description of how far it is from one point to another (measured in units of length) is called. 10. The variable which is plotted on the xaxis of a graph is called the variable.

4 An astronaut brings her lucky horseshoe on a mission to the moon. Answer the following questions about this horseshoe. 27. Would the astronaut's lucky horseshoe weigh the same, more, or less on the moon than it did on the Earth? Explain your reasoning. 28. Would the lucky horseshoe's mass on the moon be the same, greater than, or less than the mass of the horseshoe when it is on the Earth? Explain your answer. Problem 29. Calculate the number of millimeters in 2.13 kilometers. 30. How many centimeters tall is a person who is 1.65 meters tall? 31. Convert the following quantity of time to seconds. 3:45: Calculate the number of millimeters in 3.25 meters. 33. Convert the following quantity of time to seconds:
5 34. Using standard notation, express 11,256 seconds in units as hours:minutes:seconds. 35. Make a drawing to illustrate your answer to the following problem: The speed of an airplane relative to the ground depends on the airplane s speed relative to the air (the airspeed) and on the direction of the wind. For example, suppose an airplane moves at an airspeed of 100 km/h. If the air is moving 30 km/h in the same direction, the speed of the plane relative to the ground is 130 km/h. A pilot flying her airplane at a speed of 90 km/h hour directly north encounters a 45 km/h wind blowing from east to west. What is her resultant velocity relative to the ground? 36. A man runs meters in 4.00 minutes. What is the speed of the man expressed in meters per second? 37. A carton weighs 5.00 pounds. If 1.00 newton equals the weight of pounds, what is the weight of the carton in units of newtons? Essay 38. Tell why it is important to include units whenever you describe a measurement. 39. Describe how the components of a vector are most often represented graphically.

8 SHORT ANSWER 25. ANS: 240 cm/s PTS: 1 DIF: intermediate REF: section ANS: Answers may vary. Correct answers include: Example vectors: position, velocity, force, and acceleration Example scalars: temperature, speed, mass,and coefficients such as the spring constant or the coefficient of sliding friction PTS: 1 DIF: basic REF: section ANS: The horseshoe would weigh less. Weight is a measure of the pulling force of gravity, and since the gravity exerted by the moon on the horseshoe is less (by 1/6th) than the gravity exerted by the Earth on the horseshoe, the horseshoe would actually weigh less on the moon. PTS: 1 DIF: intermediate REF: chapter 03 section 03.2 STA: TEKS 4B TEKS 3A 28. ANS: The mass of the horseshoe would be the same. Mass is a measure of the amount of matter in an object, and the amount of matter in the horseshoe does not change when it is taken from one place to another.

PTS: 1 DIF: advanced REF: section ANS: The answer is 100 km/h, northwest. The speed of the plane is the resultant of the vector addition of the wind speed and the airspeed of the plane. To receive credit, the student must establish a scale and make a scale drawing representing the 90 km/h vector and the 45 km/h vector at right angles to one another.

11 38. ANS: All measurements must include units in order for the measurement to be understood. All measurements are made by comparing one quantity with another. If a measurement is given only as a number it is impossible to tell which quantity is being used for comparison.therefore, the size of the quantity which is being described cannot be determined. PTS: 1 DIF: basic REF: section ANS: To represent the components graphically, draw the vector as an arrow of appropriate length at the specified angle. Draw a vertical and a horizontal arrow from the tail of the vector. Connect these arrows to the head of the original vector with another pair of vertical and horizontal arrows. The heads of all arrows drawn should point away from the tail and toward the head of the original vector. The sides of the rectangle formed represent the size of the components. The heads of the arrows represent the direction. PTS: 1 DIF: advanced REF: section 7.1
