Suggested Reading:

The main book of this course is :

1)Fundamental of Physics: D. Halliday, R. Resnick, J. Walker. 9th edition (2010)

2) Problems in Physics I : (35 Questions)

Lectures:

** Lecture 1: (29 / 06 / 93)**

**In this Lecture we go through the first chapter
of the book. A brief history of Physics, Physics as an experimental Science,
Measurements in Physics, standard Units and the estimation in Physics is
discussed. Also the concept of measurement and error is studied. (Chapter I)**

**Lecture 2:
( 31 / 06 / 93)**

**In this lecture, we continue with the first
chapter and concept of measurement and unit-converting. Then we will start the
second chapter of the book. Introducing the concept of motion in straight line.
The average and instantaneous velocity and acceleration. (Chapter I -II)**

**Lecture 3: (
05 / 07 / 93)**

**In this lecture, we review the concept of the
dimensional analyses. we find the Energy of Planck scale by this method. Then we
study the motion in one dimension, the concept of the
average and instantaneous velocity and acceleration is restudied. (Chapter II)**

**Lecture 4: ( 07
/ 07 / 93)**

**In this lecture we study the kinematic of motion
in 2 and 3 dimensions. Solving the problem of mass moving in 3D in
constant gravitational field and a constant force field perpendicular to the
gravitational field. (Chapter III - IV)**

**Lecture 5: ( 12
/ 07 / 93)**

**In this lecture we study the circular motion.
The polar and spherical coordinates are discussed. Eventually we discuss the
concept of relative motion. (Chapter IV)**

**Lecture 6: ( 14
/ 07 / 93)**

**In this lecture, we will start talking about the
concept of force. Then we introduce the three laws of motion. Then we study the
frictional force and solve couple of examples in dynamics. (Chapter V -
Chapter VI)**

**Lecture
7: ( 19
/ 07 / 93)**

**In this lecture, we solve 2 problems in dynamics
to become more familiar with the concept of force and friction.
(Chapter V - Chapter VI)**

**Lecture 9: ( 28
/ 07 / 93)**

**In this lecture, we solve
3 problems in dynamics
to become more familiar with the concept of force and friction. (Chapter V -
Chapter VI)**

**Lecture 10: (
03
/ 08 / 93)**

**In this lecture, we start to study the
concept of energy. We discuss about the kinematic energy and potential
energy as well. (Chapter VII - Chapter VIII)**

**Lecture 11: (
05
/ 08 / 93)**

**In this lecture, we will continue to talk about
the concept of energy and conservation of energy. Stable and unstable
equilibrium is studied and couple of examples are solved.**
