### Physics 1

#### Course Description

#### General Competencies

Students completing this course will: - understand, appreciate and utilize the modern scientific methodologies associated with fundamental physical laws. - understand the importance of applications of the physical priniples in the techonological advances in various fields of science and engineering. - understand the fundamental principles of physics which will prepare them to continue education in modern science and technology at Faculty of Electrical Engineering and Computing or another university, as well as forming a foundation for life-long learning.

#### Learning Outcomes

- Analyze simple mechanical systems and solve equations of motion.
- Apply principles of conservation of energy and momentum to particle collisions.
- Apply the derivative to find minima or maxima of physical quantities in excercises in mechanics.
- Apply integrals in finding the centre of mass and moments of inertia of symmetric bodies.
- Explain the conditions of statics of rigid bodies and the equation of motion for rotation of the rigid body around fixed axis.
- Explain the principles of the Special theory of relativity.
- Apply the equation of continuity and Bernoulli's equation in simple problems in fluid mechanics.
- Explain the first law of thermodynamics and analyze thermodynamic cycles.

#### Forms of Teaching

**Lectures**Lectures are delivered to groups of approximately 120 students using electronic presentations, detailed derivations on the blackboard and demonstration experiments.

**Exams**Written mid-term exam and the final exam consist of four excercises and a number of multiple choice questions.

**Laboratory Work**Students perform six laboratory experiments, carry out the analisys of the measured data and write the final report for each experiment.

**Experiments**Lectures are supported by demonstration experiments that illustrate the concepts of physics. Approximately 30 mins / week.

**Consultations**At least once a week each professor is available to the students for consultations.

**E-learning**During the semester homework assignments are delivered to the students through the e-learning system Merlin (Moodle).

**Other Forms of Group and Self Study**In approximately 4 terms per semester additional exercise-solving skills are demonstrated by assistants.
