AP Physics 1 Name: Summer Assignment Complete the following questions and problems on your own after reading Chapter 1 in the Online Physics textbook. This assignment is due on the first day of class. It will be graded and returned to you. You will have an opportunity to ask questions about Chapter 1 before you take the Chapter 1 Test. Print this document and write the answers to the questions and problems by hand. Show your work for full credit. Some problems require the use of a ruler and protractor. Make sure that your calculator is in Degree Mode for questions 8, 9, 10, 13, 16, and 17. Sections 1. 1 1. Read Section 1.1 and in your own words, summarize your interpretation of what physics is. (1 point) Sections 1. 2 2. Read Section 1.2 and answer the following. (2 points) A. What are the three accepted units systems of measurement used in physics (don t abbreviate). B. The three base quantities are,, and. C. What are the SI units for these three base quantities? D. Speed is measured in meters per second (m/s). Is m/s a base unit or a derived unit? Explain your answer. Section 1. 3 Read Section 1.3 and answer the following questions and problems. Solve the problems by showing you work (similar to the way the examples were solved in the book). 3. How many kilometers are in 23,100 meters? (1 point) 4. Convert 7.8 milligrams to micrograms. (1 point) 5. The Statue of Liberty is 151 feet tall. Express this height in centimeters. (1 point)
6. The speed of light in a vacuum is 3.0 x 10 8 m/s. What is this speed in miles per hour? (1 point) 7. Using the chart below, determine which of the following equations are dimensionally correct. (3 points) Variable Units x meters (m) t seconds (s) m kilograms (kg) v meters per seconds (m/s) a meters per seconds squared (m/s 2 ) F kilograms meters per seconds squared (kg m/s 2 ) A. a 1 2 vt B. a F m C. x vt D. x 3at 3 E. t x a F. F mv Section 1.4 Read Section 1.4 and answer the following. 8. Find the length of side x and y. (1 point) y 25.2 m 38 x
9. Find the angle and the length of side A. (1 point) 16. 3 m 31.6 m A 10. Wil E. Coyote waits for the roadrunner on top of a 22 m high cliff. The roadrunner is 60 m away from the base of the cliff. When the roadrunner looks up at Wil E. Coyote, at what angle above the horizon does he appear? (Since the height of the cliff is much taller than the roadrunner, you may neglect the height of the roadrunner.) (2 points) Section 1.5 Read Section 1.5 and answer the following. 11. Explain the difference between a scalar and vector quantity? (1 point) 12. When an arrow is used to represent a vector quantity, what qualities of the arrow are used to represent (A) the magnitude and (B) the direction? (1 point)
Section 1.6 Read Section 1.6 and answer the following. 13. A camper hikes 12 miles east turns and walks 25 miles south. (A) Use the graphical method to find the magnitude and direction of his resultant displacement. (B) Use the component method to find the magnitude and direction of his resultant displacement. (3 points) (A) Graphical Method: (B) Component Method:
14. (A) Vector A has a value of 23 m east. What is the magnitude and direction of A? (B) Vector B has a value of 16 N south. What is the magnitude and direction of B? (1 point) Section 1.7 Read Section 1.7 and answer the following. 15. Define vector components. (1 point) 16. A displacement vector has a magnitude of 320 m and a direction of 25 south of east.
