B. Now you'll figure out a way to define the wind field more precisely. 1. The smaller kite has cross-sectional area 0.50 m. When held at point A, it feels a wind force of 3.0 N. The larger kite has exactly twice the cross-sectional area (1.0 m?) of the smaller kite. What wind force would you expect the larger kite feel at point A? Explain. 2. Now a kite of cross-sectional area 2.0 m is held at point A. What wind force do you expect it to feel? Why? 3. Here's the punch line. Each of the three kites from question (1) and (2) feels a different wind force at point A. But they should each feel the same wind field because the wind itself is the same at point A no matter which kite you hold there. Is there some number having to do with wind force and cross-sectional area that's the same for all three kites and could therefore work as a definition of wind field? This is hard; try it for a while, and if you get stuck, move on to the next question. 4. Here are two proposed definitions of wind field: (i) wind field = wind force x cross-sectional area, or (ii) wind field = wind force v cross-sectional area. Which of those definitions, if either, better captures the intuitive sense of what wind field is supposed to mean (as discussed on page 1)
