Collected: take home quizzes
Classwork: students
who were absent Wednesday completed the
take home quizzes today and turned them in to me at the
end of the period. For those who finished them on time
we went over the problems and they were recollected.
We also went over 4 more problems from worksheet C
during class. Watch units and signs. It is necessary to
actually know unit equivalents ie a N = 1kgxm/s squared
From
what I can see it appears that many people are
having problems with pre-problem force analysis and
possibly
signs. The force relationships should be worked
out after you have prethought about the direction and
magnitudes
of all forces and then drawn the free-body
diagrams.
Often bodies are in equilibrium or the net force
is not zero and will result in a change of direction or
/ acceleration.
Homework: Based on the snowday
and the number of problemd
students are having the chapter 4 test will be done on
Wednesday.
Do problems D as many as possible from the

Classwork: In class 6
problems were gone over in detail,
problems that represented a diverse set of examples from
chapter
4. (The free-body diagrams were included as were
the logic statements, which explain an analysis of mathe-
matical relationships, mathematical equivalences that set
up the approach to the problem. This is especially useful
where there isn't a single equation, but where a new
relationship
between the variables needs to be established
in order to solve for a variable that is missing from a text
equation. It is important to follow the 3 step process with
every problem, and a common place this continues to
break
down is the missing units after substitutions. The
units
are a big place that breakdown occurs and students
don't recognize it since they are not following the units.
When we go over problems like this in class it is imper-
ative
that they be copied into your notes so that you and
your study team can work to resolve areas of confusion
left over from class. It is also useful to come in for help
after school or during makeup day on Monday.)
Answers were given for the 10 problems on HW Problem D
and
problem 9 was explained in detail.
Homework: Test chapter 4,
study the 4 returned quizzes done for
chapter 4, the answers were reviewed for all of the ques-
tions during class. Use them for content objectives and
math examples. Form study groups, look at online tutorial
videos, read the chapter summary, review the math equa-
tions, look over the free body diagram concepts, come in
after school. Everyone will feel challenged by physics
it is how you actually work to get up to speed to under-
stand the concepts that makes a difference. Get tutors
through the national honor society, spend more time work
ing though dfficulties, get more experiences working
problems.
Good luck folks...
