Tutoring Help for Phys 111

• Listed on course web page

Tutoring through the Physics Department is
available according to the schedule below TA
Phil Lo, pyl3_at_njit.edu FRIDAYS 1130-230pm
ROOM 409 Tiernan MONDAYS 230-530pm Room 409
Tiernan EXCEPT weeks that we have common exams.
For the weeks that we have common exams, instead
of Monday (when we have the exam), tutoring will
be available the Saturday BEFORE the exam from
noon-3pm, also in Room 409Tiernan.

Common Exam 1

• TODAYs material WILL BE on the common exam.

How will you spend your Summer?

• Consider performing research at a National
  Science Foundation (NSF) sponsored Research
  Experience for Undergraduates (REU) site.
• Ask in your department who has NSF funding. The
  faculty member can request Summer funds for
  students so that you can work at NJIT.
• Go to the national REU site and spend the Summer
  in California, Florida, Michigan, Maryland, New
  Mexico, etc.

Due dates in March. Typically sophomores to
juniors are accepted. Start thinking about your
Summer plans NOW!

Due dates Friday, April 4th, 2014.
I am looking for students with experience with
the RASBERRY PI computer, ANDROID Applications,
for a project to interface 16 different cameras
with a computer or smart phone. IF YOU HAVE
EXPERIENCE IN these areas, contact

Iclicker Question 1
In the recent movie Inception starring Leonardo
DiCapri (playing Cobb), what allows the laws of
physics to be violated?

1. Robots invade our minds and program our thoughts
2. An anti-gravity machine
3. The laws of physics are shown to be invalid.
4. Its all a dream
5. We are all in the Matrix, so it really doesnt
   matter does it?

Iclicker Question 2
Which of the following choices of coordinate
systems would be best if the acceleration a is
varying in magnitude, but constant in direction?

1. B) C) D) E)It doesnt really matter,
   because I am dreaming.

Projectile Motion
15
Iclicker Question 3
which of the following statements is FALSE
concerning the projectile motion illustrated in
the figure?

1. At the peak height of the projectile motion, the
   magnitude of the velocity is zero
2. At the peak height of the projectile motion, the
   particle is travelling parallel to the ground
3. The height of the projectile when it hits the
   ground is zero.
4. The velocity of the projectile when it hits the
   ground is the same as when it is launched.
5. In order to hit a particular range, the required
   magnitude of launch velocity and launch angle are
   not unique.

17
If projectile is launched just as target drops,
the projectile still hits target target and
projectile fall at same rate.

Federicis Rule of Physics 1
Cartoons do not teach you proper physics.
Federicis Rule of Physics 2
You can learn proper physics by playing video
games or by watching science fiction movies.
