Er der nogen som vil se mit abstract igennem? Jeg skal nemlig aflevere min SRP-opgave i morgen.

This paper examines the subject harmonious oscillations. My aim of this assignment is to develop a mathematical model describing damped harmonic waves of a mass suspended from a spring in a liquid.
There have been made measurements of a spring with lot and at least two different fluids, and determine their oscillation periods and amplitudes. Comparison theory, the mathematical model and experiment test results. And finally evaluate and discuss the experiment's systematic and random deviations.
This paper is also giving a description of Hookes Law with emphasis on the combination with harmonic oscillations. There are different kinds of theories, which include the theory of proofing the second order linear homogeneous differential equations of the form y^''=my and y^''+ay^'+by=0.
Moreover, this paper describes a theory of a body moving in water, as illustrated by an experiment.
Four physical experiments will be made, to examine whether there is a match between theory and practice. Two of the experiments are going on to make measurements of a spring with a weight of two different liquids to determine the oscillation periods and amplitudes.
Using the theories and experiments can be concluded that the frictional force is proportional to the velocity of the object. And after completing the experiments can be concluded that the theory of differential equations actually is true.
