Lectures:

** Lecture 1: (21/2/2013)**

In this lecture, we talk about the Physics as an experimental Science. The concept of measurement, falsification, experiment, accuracy in measurements, quantification is discussed. We talk about the history of Science and the main revolution which was happened in by Newton, Galileo, Kepler, Copernicus and ... Then we argue about the concept of Newtonian Science and Bacon Science. Then we talk about the fundamental units of nature: Mass, Length and Time. About measurements, approximation and ... Finally we start the Mechanics by introducing the Kinematics and Dynamics concept.

For this lecture you can read: Fundamental Physics, Halliday, Resnick, Walker (Halliday hereafter) Chapter 1, For the concept of Newtonian and Baconian Science you can read ایران 1427: رضا منصوری طرح نو چاپ سوم 1383

** Lecture 2:
(22/2/2013)**

In this lecture we talked about the constant acceleration motion. The concept of velocity, acceleration, and the differential-integration method to derive the motion equations from first principles. Then we talked about coordinates, vectors and dot product. Finally we introduce the spherical coordinate, the transformation of this coordinate to Cartesian and the concept of orthogonality.

For this lecture you can read: Halliday Chapter 1-2

**Lecture 3: (28/2/2013)**

In this lecture we discuss the kinematic in 2-3 dimensions and the second law of Newton is discussed we must set a framework to solve the dynamical equations

For this lecture you can read: Halliday Chapter 3-4

**Lecture 4 : (1/3/2013)**

In this lecture first we study the motion in 2 and 3 dimensions wth emphasis on the concept of friction. Then we talk about Kinetic Energy, the concept of energy conservation and we introduce the lagrangian formalism.

For this lecture you can read: Halliday Chapter 5-6

** Lecture 5 : (7/3/2013)**

In this lecture we continue studying the concept of lagrangian and how we can use it as new method to solve the dynamical problems.

For this lecture you can read: Halliday Chapter 7 and Lecture notes in class

** Lecture 6 : (14/3/2013)**

In this lecture first we talk about the concept of Potential Energy and its relation to the force. Then we introduce the concept of linear momentum.

For this lecture you can read: Halliday Chapter 8 -9

**Lecture 7: (15/3/2013)**

**In this Lecture we talk about the conservation
of linear momentum, and show we can use it as a technique to solve mechanic
problems.**

For this lecture you can read: Halliday Chapter 9

**Lecture 8:
(11/4/2013)**

In this lecture we define the concept of the centre of mass and also review the conservation of linear momentum for closed, isolated systems.

For this lecture you can read: Halliday Chapter 8-9

** Lecture 9:
(12/4/2013)**

In this lecture we discuss a couple of problems which are related to topics of motion in 2D and 3D Conservation of energy, Conservation of Momentum, Collisions and the trajectory of a particle.

For this lecture you can read: Halliday Chapter 8-9 and reviewing 5-6

** Lecture 10 :
(18/4/2013)**

In this lecture we solve problems on Conservation of Energy and Momentum. We start the subject of rotational motion, arguing that how we can relate the rotational parameters to the linear ones. Then we discuss the concept of moment of Inertia and the way it is related to calculation of kinetic energy

For this lecture you can read: Halliday Chapter 10

Lecture 11: (19/4/2013)

In this lecture we review the concept of rotational acceleration and we study the motion in this case. We show and develope a method to find the moment of inertia for solid objects. Cuple of problems is solved.

For this lecture you can read: Halliday Chapter 10
