Answer the Reading Questions below. Please answer each question.

1. What are the four major areas of physics that you will study over the next few years as a physics major?

2. What are the SI units for length, time and mass?

3. If you were traveling 65 miles per hour, how fast would that be in meters/second?

4. If v stands for velocity, m for meters, and s for seconds, what do you know must be wrong with this equation: v = 25 m2/s?

5. How many significant digits are usually used in an "order of magnitude" calculation?

6. Describe how vectors are added graphically?

7. If A, B and C are vectors that are not all parallel to each other, and C = A + B, can it ever be true that C = A +B? (Note that bold face, like V means a vector, while italics, like V means a scalar. The magnitude of a vector is a scalar.)

Yes
No

8. When adding vectors analytically (with numbers), under what circumstances can you add the x component of one vector with the y component of another vector?

9. Describe in words the physical interpretation, or definition, of the scalar product of two vectors.

10. Can any component of a vector ever have a larger magnitude than the magnitude of the vector itself? Under what circumstances could the magnitude of a vector component equal the magnitude of the entire vector?

Final Question: (This question must be answered to receive any credit). What is one thing from the chapter that you didn't understand or need clarified?
