## ING2302 Dynamics and Chemistry

The course will give the cadet broad knowledge of mechanics (with an emphasis on dynamics, rotational motion, oscillations and waves) and knowledge of inorganic chemistry. This forms an academic basis in dynamics and chemistry on which other courses are based.

The course covers the following academic content: rectilinear kinematics (position and displacement, velocity and change of velocity, acceleration, equations of motion with constant acceleration, applications of derivatives and integration), curvilinear kinematics (vectors, vector components, vector functions, vector calculation, position vector, displacement vector, velocity vector, acceleration vector, tangential acceleration and centripetal acceleration, equations of motion in vector form and component form, projectile motion, uniform and nonuniform circular motion, Cartesian coordinates and cylindrical coordinates), forces (Newton’s laws in vector form and component form, composite systems, rectilinear and curvilinear motion, projectile motion with air resistance), momentum and impulse (conservation of momentum in one and two dimensions, the impulse-momentum theorem), energy and work (kinetic energy, potential energy in a gravitational field and for elastic springs, mechanical energy and energy conservation, work and change of kinetic or mechanical energy, power), rotational kinematics (angular velocity, angular acceleration, equations of motion at constant angular acceleration), centre of mass and moment of inertia (by summation or simple integration, parallel-axis theorem), energy and angular momentum (rotational energy, energy conservation for rotational motion, angular momentum for a spinning object), rotational dynamics (torque, Newton's second law for rotational motion, work and change of rotational energy, power), oscillations and waves (harmonic oscillations, free, damped and forced oscillations, resonance, harmonic waves, dispersion relations for water waves, intensity, sound level, decibel scale, Doppler effect, superposition, beats, wave reflections, standing waves, oscillations and waves in complex form (phasor), standing-wave ratio (SWR), acoustics, particle oscillations and pressure oscillations, sound pressure, transmission and reflection at an interface), chemistry (atomic structure and periodic system, chemical compounds, nomenclature and chemical bonds, solutions, gases, chemical equations and quantitative calculations, combustion reactions, complete combustion reactions, chemical equilibrium, thermodynamics and kinetics, acid-base reactions and redox reactions, electrochemistry, galvanic series, galvanic cells, electrolysis, corrosion forms and corrosion control).

The course follows STCW code table A-III/2 and the STCW function marine engineering at the management level.

The course is planned to be given by a civilian university.

Knowledge

After completing the course, the cadet is able to:

- describe key concepts and methods in dynamics and chemistry
- explain relationships between various phenomena in dynamics and chemistry and practical applications

Skills

After completing the course, the cadet is able to:

- apply relevant terminology and a system of formulas
- account for various phenomena in dynamics
- use that knowledge to create mathematical models of selected phenomena in dynamics
- reason systematically, solve mechanical/chemical problems and explain his/her results
- set up chemical reaction equations and apply them in practice in hydrocarbon combustion
- explain what a reaction rate entails

General competences

After completing the course, the cadet is able to:

- use scientific methods and a scientific way of thinking
- communicate in writing and orally about physics and chemistry

The dynamics segment and the chemistry segment make up 75% and 25%, respectively, of the entire course.

Examination is carried out according to the Regulations for Admission, Studies and Examinations (in Norwegian, “Forskrift om opptak, studier og eksamen”) at the Norwegian Defence University College.
