Answer short answer questions such as:

The hare goes very fast for brief intervals, but stops frequently, whereas the tortoise plods along steadily and finishes the race ahead of the hare. (a) Which of the two racers has the greater average speed over the duration of the race? Explain. (b) Which of the two racers is likely to reach the greatest instantaneous speed during the race? Explain.

Examples of Outside Assignments
For each hour of lecture, students are expected to spend at least 2 hours outside of class doing required work such as viewing pre-lecture videos/reading required materials, completing short quizzes on the material, solving simple mathematical problems that predict/explain the behavior of physical systems and answer conceptual questions about physical phenomena.
Sample Assignment: Collect a variety of small objects such as coins, pencils, keys, and bottle caps. Ice cubes, if they are available, also make excellent test objects. Try sliding these objects across a smooth surface such as a tabletop or floor, being as consistent as possible in the initial velocity that you give to them. a. Do the objects slide the same distance after they leave your hand? What differences are apparent, and how are they related to the nature of the surface and size of the objects? Which objects come closest to demonstrating Newton's first law of motion? b. What factors seem to be important in reducing the frictional force between the objects and the surface upon which they are sliding? If you see some general principle at work, test this idea by finding other objects that would support your hypothesis.
