Blue Book
Read and take notes on section 4.5 (p.48-50) and all of chapter 9 (p.122-132). Pay attention to bold words, italics, pictures, and diagrams. Then answer these questions on a separate paper to be turned in:
p.56 # 9 &12
p.133 #2, 3, 6, 8, 12, 17
If you finish early, do some more of the Review Problems or Think and Explain problems. I will give extra credit for any extra problems done correctly and answered in complete sentences.

Does a 2 kilogram rock have twice the mass of a 1 kilogram rock? Twice the inertia? Twice the weight (when weighed in the same location?)
An elephant and a mouse would both have the same weight in gravity-free space. If they were moving toward you with the same speed, would they bump into you with the same effect? Explain.
Does a child on a merry-go-round revolve or rotate around the merry-go-round's axis?
At a given rotational speed, how does linear (or tangential) speed change as the distance from the axis changes?
When you whirl a can at the end of a string in a circular path, what is the direction of the force that acts on the can?
If the string that holds a whirling can in its circular path breaks, what causes the can to move in a straight-line path - centripetal force, centrifugal force, or a lack of force? What law of physics supports your answer?
For space habitats spinning at the same rate, what is the relationship between simulated gravity and the radius of the habitat?
