Teaching Notes

[admin]

Students can be expected to need practice to exert
constant amounts of force on moving objects. Only
semiquantitative comparisons of the amounts of
acceleration (e.g., low, higher, even higher) which
result from varying the amount of force (while mass is
held constant) and from varying the amount of mass
(when force is held constant) are intended.
Direct all students to silently read the For You To
Read section. Then conduct a brief discussion of the
assumption presented in the section. You may wish to
point out that assumptions represent beliefs which
may be argued, but not proven as “right” or “wrong.”
Another example of an assumption which could be
used for the discussion is “There is a tooth fairy.”
You may wish to see if students really believe that
gravity treats all athletes equally by probing students
about the “hang time” of basketball stars.

Has anyone worked the Physics to Go Plus.  Part c ?  I apparently have a moment of lapse  of intelligence?
