1. In the United States, we often use the imperial system of measures. In the imperial system, distance, for example, is measured in units of inches, feet, yards, and miles. Explain how the metric system, with its standardized prefixes, make unit conversions simpler.
2. Give an example of a time when it is helpful to use scientific notation, and an example of time when it is not.
3. Why are scatter plots helpful in quickly determining a qualitative relationship that may exist in a data set?
4. Anthony and a friend from physics class are talking about scalars and vectors. Anthony argues that scalars are not useful, because they always contain less information than vectors. Is this an accurate statement? Explain your answer.
5. Clarence is taking his dog for a walk around town. After wandering around for an hour, his mother calls him, telling him dinner will be served soon, and asks him how far away he is. What value would be more helpful for him to give, his distance or his displacement? Explain your answer.
6. Sheila received a speeding ticket when she was driving to her job. Was this ticket issued due to her average velocity during her drive or her instantaneous velocity. Explain your answer?
7. Does a negative value for acceleration always mean that the object is slowing down? Explain your answer.
