Overview

Introducing the student to the science of mechanics and its relationship to the rest of physics branches, motion in one dimension, in the plane and in space, motion of bodies under the influence of a variable force, dealing with a system of particles through the center of mass, the study of dampened and forced vibrations, motion of rigid bodies, gravity and centripetal forces.

Intended learning outcomes

At the end of the course, the student should be able to:

1. Uses mathematical skills in the treatment of mechanical problems.

2. Apply his knowledge of the principles of kinematics to describe the motion of a system of particles through the center of mass.

3. Detects the dynamics of dampened and forced vibrations.

4. Calculates the speed, acceleration and momentum of multibody systems.

5. Uses the laws of circular motion to solve problems.

6. Develops his communication abilities to work within a team.

7. Acquire the ability to write scientific reports and articles on the topics of the course

8. Selects the positive skills towards self-learning.

Teaching and learning methods

  • Lectures.
  • Discussion and dialogue.
  • Tutorials and exercises.

Methods of assessments

The methods of evaluating students in this course are distributed as follows:

o Semester works (40 marks) are divided as follows:

  • First written exam (objective questions and problem) (15 marks).

  • Second written exam (objective questions and problem) (15 marks).
  • Scientific activities (e.g. weekly tests, reports discussion) (10 marks).

o Final: written exam (60 marks).
