# Physics 2008-2009 - REA2041 - 10 ECTS

## On the basis of

REA1042 - Mathematics 10 - Functions with one variable

## Expected learning outcomes

The students are supposed to:

• analyse and model problems within classical mechanics, electromagnetism, fluid mechanics and thermal physics
• evaluate the correctness of their own calculations and work
• exhibit understanding for relations between theory and practical problems within subjects from electrical, computing, civil and mechanical engineering

## Topic(s)

Fluid mechanics:

Hydrostatics: Pressure. Buoyancy. Forces on submerged surfaces. Hydrodynamics: The equation of continuity. Bernoulli's equation. Laminar and turbulent flow. Resistance and forces of flow.

Thermal physics:

## Form(s) of Assessment

Written exam, 4 hours

Alphabetical Scale, A(best) – F (fail)

## External/internal examiner

Evaluation of exam work is done by course responsible. External examiner is used periodically (every 3 to 4 years) for evaluation of exam work and for production of exam exercises.

## Re-sit examination

A separate re-sit exam is arranged.

## Examination support

Accepted calculator.

## Coursework Requirements

Exercises (3-5 during the term)

Detailed plan for required exercises is presented at course start-up. Three-semester students shall hand in 2-3 additional exercises in the three-semester period during the autumn.
