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@njit.edu

FRIDAYS 11:30-2:30pm ROOM 409 Tiernan

MONDAYS 2:30-5:30pm 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

• TODAY’s 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!

How will you spend your Summer?

Consider performing research at NJIT over the Summer

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 mefederici@njit.edu

Iclicker Question #1

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

A) Robots invade our minds and program our thoughtsB) An anti-gravity machineC) The laws of physics are shown to be invalid.D) Its all a dreamE) We are all in the Matrix, so it really doesn’t matter does it?

Parallel and Perpendicular Acceleration

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?

A) B) C) D) E)It doesn’t really matter, because I am dreaming….

A)

x

y

B) C) D)

Projectile Motion

Iclicker Question #3

which of the following statements is FALSE concerning the projectile motion illustrated in the figure?

A) At the peak height of the projectile motion, the magnitude of the velocity is zero

B) At the peak height of the projectile motion, the particle is travelling parallel to the ground

C) The height of the projectile when it hits the ground is zero.D) The velocity of the projectile when it hits the ground is the same

as when it is launched.E) In order to hit a particular range, the required magnitude of launch

velocity and launch angle are not unique.

x

y

Vo

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

Federici’s Rule of Physics #1

You can learn proper physics by playing video games or by watching science fiction movies.
