Use the chapter on oscillations in your textbook as a reference.

1. Which chapter in your textbook deals with oscillations of systems such as a block on a spring and pendula of various kinds? (Give the number only.)

2. For an ideal simple pendulum, the bob is taken to be a point mass swinging at the end of a massless string. The length of the pendulum is the distance from the point of support to the point bob. These conditions can only be approximated in the laboratory. Between what two points will you measure the length of the pendulum that you set up for your experiment?

3. When you measure a time interval such as the period of a pendulum with a stopwatch, there will be unavoidable timing errors in deciding when to start and stop the stopwatch. Describe a technique to minimize the timing error inherent in measuring the period of a pendulum.

4. Under what conditions does an object exhibit simple harmonic motion?  Answer this question for SHM in general, but be specific in describing the conditions.

5. Give the page number of your text on which question 4 is answered.

6. Under what condition does a simple pendulum closely approximate simple harmonic motion?

7. Give the page number of your text on which question 6 is answered.
