Physics 1 for Geodesists

The module "Physics 1 for Geodesists" introduces students of Geodesy and Geoinformation to basic experimental physics. This module covers classical mechanics, oscillations and waves as well as basic concepts of thermodynamics.

Index of contents:

• Introduction to physics
• historical review
• measuring units
• measurement accuracy
• classical mechanics with one point particle
• equations of motion
• Newton's laws, momentum, angular momentum
• Kepler's laws, planetary motion
• friction, pseudo forces
• systems of point particles
• collisions and conservation laws
• extended bodys
• moment of inertia
• gyroscope
• friction and tides
• gases and fluids
• kinetic theory of gases
• Maxwell Bolzmann
• Bernoulli
• laws of thermodynamics

After successful completion of the module the students are able to:

1. remember basic concepts of mechanics
2. remember methods of experimental physics
3. understand basic concepts of physics
4. solve physical problems by themselves
5. routinely apply mathematical methods
6. critically review physical phenomena
7. develop a deep understanding of physical phenomena

mathematical skills as required to pass the Abitur:

• geometry
• vector analysis
• differential calculus
• integral calculus

The module consists of a lecture and a tutorial.

Lecture:  ex-cathedra teaching with demonstration experiments

Exercise to Physics I for Geodesy and Geo-Information:  students get problem sheets and try to solve these problems by themselves before coming to the tutorial. During the tutorial sample solutions are presented by students or the lecturer and also possible alternative ways to solve to the problems are discussed. Students who present at least two solutions per term during the tutorial and who work through the problem sheets regularly (i.e. they miss at most two problem sheets) can get a bonus of 0.3 on the grade of the module. Following these tutorials will help the students to be prepared to solve the problems during the written exam.

The differents teaching formats are closely intertwined and the lecturers are in constant exchange.

During the lecture a powerpoint presentation is used and some contents are explained using the blackboard. Additionally some example videos are shown during the lecture. For the exercises problem sheets are prepared. An e-learning course in Moodle exists. Presentation slides and problem sheets as well as sample solutions to problems which have already been discussed in the tutorials are available on this platform.

There will be a written exam of 60 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using calculation problems and comprehension questions.

For example an assignment in the exam might be: The exam is held in German: Ein Hochstrahlbrunnen spritzt das Wasser bis in eine Höhe von 140 Metern über der Düse. a) Berechnen Sie die Geschwindigkeit v0 (in km/h), mit der das Wasser aus der Düse strömen würde, wenn keine mechanische Energie verloren ginge. b) Berechnen Sie die Geschwindigkeit v1 (ebenfalls in km/h) des Wassers in halber Höhe. c) Erläutern Sie, warum der tatsächliche Wert der Geschwindigkeit des aufsteigenden Wassers mit ca. 200km/h für v0 über dem berechneten Wert liegt. d) Berechnen Sie welche Höhe die Fontäne erreichen würde, wenn v0 nur halb so groß wie der in Aufgabenteil a) berechnete Wert wäre. e) Pro Sekunde durchlaufen die 500 l Wasser die Düse. Untersuchen Sie, wie lange die Fontäne mit einer Energie von 10.000 Kalorien betrieben werden kann.

In the exam the following learning aids are permitted: pocket calculator

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

There will be a bonus (one intermediate stepping of "0,3" to the better grade) on passed module exams (4,3 is not upgraded to 4,0). The bonus is applicable to the exam period directly following the lecture period (not to the exam repetition) and subject to the condition that the student passes the mid-term of

• working through the problem sheets regularly (missing most two problem sheets)
• presenting at least two sample solutions to the problems to the group
