Subject Description
This course provides a quantitative introduction to physics science for both mechanics and fluid mechanics for science and engineering students. Students will be exposed to the various components of the mechanical sciences including motion, law of motion, force, linear momentum and collision, fluid instruments measurement . , physics is the branch of knowledge that studies the physical world. Physics investigate objects as small as atoms and as large as galaxies. They study the natures of matter and energy and how they are related.
2. Require Background or Experience
Learning objectives are developed to assist students in understanding the main goals of the course. During the semester, teaching and learning activities are designed with these objectives in mind. Assessment activities play the role of measuring to what level students achieved these learning objectives.
3. Subject Objective
* The goal of this course is not to make you a physicist. It is to give him an idea of the way physicist view the world.
* To have the satisfaction of understanding and even predicting the outcome of the activites occurring all around you.
* To know enough about physics so you can have a rewarding career in technological wold.
* To be able to make informed decisions as a citizen in an increasingly complex age, to learn to ask questions.
4. Reading materials and Reference
The course textbooks are. [Physics principles and problems (Merrill), Fundamentals of physics 8th edition( Jearl Walke), ÇÓÇÓíÇÊ ÇáÝíÒíÇÁ(ÏÇÑ ÇáÝßÑ ÇáÚÑÈí)] . It is very important that you do the assigned readings from this book prior to class, as inclass activities, quizzes and discussions will assume the reading has been completed. While I realize that purchasing two books is expensive, and not to mention heavy to carry around, these companion books should serve you well in both this class, and throughout your future studies in physics. Additional reading material that may be help.

11.Sample of Questions and Answers:
Q 1: Average and instantaneous acceleration
The velocity of a particle moving along x axis varies in time according to the expression
vx = (40 – 5t2) m/s where t in second. (A) Find the average acceleration in the time interval
t = 0 to t = 2 s. (B) Determine the acceleration at t = 2 s.
Solution:
(A) Average acceleration: ti = 0 s and tf = 2 s
vxi = (40 – 5t2) m/s = [40 – 5(0)2] m/s = 40 m/s
vxf = (40 – 5t2) m/s = [40 – 5(2)2] m/s = 20 m/s
?x = (vxf – vxi) / (tf – ti) = [(20 -40) m/s] / (2 – 0) = - 10 m/s2
(B) Instantaneous acceleration:
at t =2 s
vxi = (40 – 5t2) m/s
ax = dvx /dt = 0 -10 t = -10 m/s2
at t = 2 s
ax = dvx /dt = 0 -10 t = -10 (2) m/s2 = - 20 m/s2
Q 2:
The Cartesian coordinates for a specific point are (x,y) = (- 3.5,2.5) m. Find the polar coordinates for this point.
Solution: y
r =( x2 + y2)½ = [(-3.5)2 + (2.5)2]½ = 4.3 m
tan ? = y/x = 2.5/(-3.5) = - 0.714 (- 3.5,2.5) m 2.5 m
? = tan -1(-0.714) = 144.5o r
? = 144.5o /57.3o = 2.52 rad ? x
i.e., (r,?) = (4.3 m, 2.52 rad) -3.5 m
