Materials needed for each class: Pencil and pen, Physics notebook with extra paper,
scientific calculator (preferably graphing), textbook, and all appropriate handouts
announced. It is highly recommended (not required) that you have a tablet or laptop for
this course because most of the homework is online.
How you will be graded: You are expected to chart your progress and keep track of
your own grade. Knowing your percentages in each category, the formula below may be
used to calculate your own grade at any given time throughout the marking period.

Tracking your grade: Home Access Center will be updated approximately one week
following an assessment. There is also an Excel template available on my website that
will calculate the grade for you if you would like faster information.
Attendance policy: You are responsible to get the notes that you missed and complete
whatever assignments you missed. You will not always be reminded. Making up missed
work is your responsibility. If you cut class, you will receive a zero for whatever was
completed on the day you cut. You are responsible to make up missed labs available on
the Moodle portal, or set up a time to make labs up in the classroom. Use the class
website and Moodle to keep up if you are out. You are expected to be aware of what was
missed during an absence prior to returning to class.
Notebook suggestions: Your notebook should be a three-ring binder of about 1.5-inch
width. The notebook is not graded, however, the course is cumulative in nature, and the
College Board requires that you keep a lab portfolio for this course.
Classroom Rules
1. One person speaks at a time. You are to respect the instructor and one another at all times in
the classroom. Raise your hand when you want to speak. Use good manners and be polite!
2. Act appropriately while in the classroom. This means no foul language or discussions that
are not appropriate for school. No talking negatively about other people. No gossip or
drama!
3. Hands off equipment. No touching any gadgets or equipment unless told to do so by an
instructor. When you do use equipment, you may only use it for the intended use so that it
does not break, and we keep everybody safe.
4. Keep the room clean and neat. This means no graffiti on any school property. Throw away
all of your garbage. No food or drink in the classroom. Push chairs in nicely when you
leave.
*Rules and procedures may be changed if the instructor determines it is necessary.
* In the event of a substitute or student teacher, the same rules, procedures, and expectations
apply.
Homework: Homework will often be collected and graded, or just checked for
completion. Homework will not always be assessed. However, you will not always
know when it will be assessed, so have it done! It is your responsibility to be aware of all
assignments and progress before you return from an absence. Use the website, Moodle,
and WileyPlus portal to print out any documents that were handed out during class.
Quizzes: Pop quizzes may be given at any time.
Extra Credit: Extra credit will be offered periodically by Mr. Flueso on a class-wide
basis. Bonus assignments will be part of your “graded assignments” grade.
What to do if you feel lost: If you ever become overwhelmed, or feel that you are falling
far behind the class, please set up a time to meet with Mr. Flueso and discuss an action
plan to get you back on track.
Good luck!
Course Overview
AP Physics C is the second of a two year sequence that is designed to prepare students to
take the AP Physics C examination. It begins by integrating the use of calculus
(differentiation and integration) into the AP Physics B topics of mechanics and electricity
& magnetism. This allows students to solve calculus based problems (SC8). This course
emphasizes problem solving in the context of the principles of physical laws and
principles; as well as the ability to apply that knowledge and skill to phenomenon in
either an experimental or theoretical setting. Great attention is given to strengthening and
reinforcing the natural connections between the sciences and with mathematics. Proper
preparation to take this course includes the completion of Physics Honors, AP Physics B.
While it is best if Calculus is completed prior to the start of this course; it is possible to
take it in parallel if the student is able to commit additional time and effort. Students will
be involved in problem solving activities on an individual, small
group and large group basis. Through this process the ability to read and understand
problems, break them down into their component parts and then create and present
solutions will be developed. These same skills will be developed with activities in the
physics laboratory. In that case, problem solving will be done in real time with hands-on
problems. Much of the work done in the laboratory will include the gathering of data
through PASCO electronic sensors. That data will be configured by the students using
the PASCO software and then analyzed using that software as well as a number of
compatible programs, including Excel and LoggerPro. Through this process both
analytical techniques as well as technological capability will be developed.
