*Unless otherwise stated, you will ALWAYS NEGLECT AIR RESISTANCE and friction for every question in this
midterm.*
PLEASE NOTE: For all MATH QUESTIONS, the actual NUMBERS USED are subject to change on the midterm.
Remember – all questions from the midterm will come WORD FOR WORD from your old tests/ quizzes.
(answer choices/order may be different than actual tests)
Below, you will see a selection of old test questions. All questions on the midterm (*except questions from
Chapter 8*) WILL BE FOUND in this packet; however, this packet contains more questions than you will see
in the midterm.
*You will not find questions from Chapter 8 on this packet because you have not yet taken your Ch 8
assessment. Please keep in mind that ALL QUESTIONS on the midterm pertaining to Ch 8 WILL be pulled
WORD FOR WORD from your Ch 8 assessment *
Midterm is worth 10% of your ‘grade to date’ or ‘overall grade;’ it will consist of 100 multiple choice
questions worth 1 point each. If you choose to complete the midterm on Scantron, you will get your grade
back the day you take the midterm. If you choose to write on the test like we normally do in this class, you
will get your midterm grade when you receive your report card.
Midterm Frequently Asked Questions
1. What is the format of the midterm? The midterm will consist of 100 questions. These questions will appear in a

4.
5.
6.
7.
multiple choice format. All possible midterm questions are listed in your review packet, with the exception of
questions from Chapter 8.
Will I have extra time at the start of class for any last minute review? No – we will begin with the midterm
ASAP.
What do I do when I walk into the room on midterm day?
 Take out something to write with and erase with. Take out an approved calculator, or borrow one.
 Place ALL BAGS AND ANY OTHER MATERIALS (including snacks/ drinks) in the front right corner of the
room
 Place your Physics Midterm Cheat-Sheet in the IN BOX. Teacher will review and if approved, will hand
back for your use on the midterm
Will I be given the formulas for this midterm? Yes, you will be given a FORMULA CARD to use DURING the
midterm; formula cards will have ID numbers at the top, and you will be given the card that corresponds with you
Physics ID number. You must return this card after you have taken the midterm. **See old tests for your
formulas *
Can I bring any notes with me? You will be granted the privilege of using an approved “Physics Midterm CheatSheet.” This is a form on ONE SIDE of a single sheet of 8.5x11” computer paper (*You will get this form in class
the week before midterms*). When you enter the room on exam day, you will place your completed Cheat
Sheet in the IN BOX. The teacher will sign off on each individual cheat sheet and give it back to you to use on the
midterm. Using anything other than the ONE SIDE of the approved form that was given to you in class will be
considered CHEATING and your “Cheat-Sheet” privileges will be revoked for both the midterm AND final.
Do I have to use Scantron? No, you do not have to use Scantron. If you do not use Scantron:
 You will write your answers directly ON the test.
 You may use the paper on the test itself for extra work/ calculations etc.
 You will not get your midterm grade until Genesis is back up
Can I use Scantron if I want? Yes, you may. If you use Scantron:
 You MAY NOT WRITE on the test itself; you will put all final answers on the Scranton sheet. **** #2
pencil ONLY! And bring a good eraser so that you are not marked wrong for smudges!****
 You will see the teacher for scrap paper for any calculations. ALL scrap paper must be returned with your
midterm. The teacher will hand you a piece of scrap paper and record that you took a piece; you may
continue to see the teacher for more paper as needed. The teacher will record the total piece of scrap
paper you have taken; that same number MUST be returned with your test. If you do not return the
same number of papers, it will be considered cheating.
 You will get your midterm grade ASAP. Usually, the teacher is able to grade the Scantrons that block. If
this is not possible, then you can stop by at the end of the school day, email the teacher, or stop by the
following school day for your grade.
8. Am I allowed to use a calculator? You may use a NON-GRAPHING calculator (graphing calculators must be
checked by Ms. Bones). iPods, cell phones, or any other multi-functioning devices will not be permitted. You
may borrow a calculator from the teacher on a first come, first served basis.
9. Can I listen to my iPod? Absolutely NO electronic devices (other than approved calculators) will be permitted to
be used UNDER ANY CIRCUMSTANCES during midterms. When you enter the room, ALL BAGS will be placed in
the front of the room. The only items you may have at your desk are a pen/pencil, eraser/white-out, and an
approved calculator. The teacher will pass out all exam materials, including formula cards & approved “CheatSheets” – remember, you will be turning these in as soon as you walk into class so that the teacher can approve.
10. What do I do when I am done with my midterm? You will HAND all materials (including cheat sheet and formula
card) DIRECTLY to the teacher; you will then silently return to your test seat. Make sure you bring something
with which to stay SILENTLY occupied! (bring a book, study materials for another midterm, magazine, etc…NO
IPODS!!!)
 There will be NO WARNINGS to stop talking when the midterm is in session. If you speak before the
teacher gives you permission, your name will go up on the board with a “check” mark next to it. Each
time you speak, another check will be added. You will lose 1 point from your midterm for each check
mark you accumulate. The teacher will NOT verbally correct you, as this is even more of a distraction.
