What strikes you about this episode? Tell your neighbor what you noticed.
-
Caleb’s initial explanation (line 4) makes it sound a little like the force is a substance emanating from the fan. Would it be a problem if someone was thinking of force that way at this point in the tutorial, or not?
-
In line 16, Deb makes an analogy with a Newton’s third law example. What analogy does she make?
-
Bridget also makes an analogy: she says something about a bowling ball and a golf ball that experience the same drag. Is she agreeing with Caleb, Deb, both, or neither?
