Physics 4 - Laboratory work (2 cr)

Evaluation scale

0-5

Content scheduling

Kurssin alussa käsitellään mittausten suorittamiseen sekä mittaustulosten laskemiseen ja virhearviointiin liittyvää teoriaa koko opetusryhmän osalta. Teoriaosuuden jälkeen siirrytään suorittamaan mittauksia, minkä pohjalta raportoidaan mittaustulokset.

Objective

Purpose: The operation of many applications is based on experimental data. The utilization of the data requires an error estimation of the results derived from the data. During the course, experimental data is measured to evaluate the use of data-derived results in different applications.

EUR-ACE Competences:
Knowledge and understanding 
Engineering practice
Investigations and information retrieval

Materials

Mittaustuloksista laskettujen virheiden arvioinnissä hyödynnetään kirjaa:

Taylor, J. R. An introduction to error analysis: The study of uncertainties in physical measurements (2nd ed.). ISBN: 978-0935702750.

Kurssilla jaetaan tarkemmin työkohtaiset ohjeet.

Teaching methods

Employer connections

Kurssin sisältö pyritään kytkemään työelämässä esiintyviin ongelmiin.

Completion alternatives

Hyväksilukemisen menettelytavat kuvataan tutkintosäännössä ja opinto-oppaassa. Opintojakson opettaja antaa lisätietoa mahdollisista opintojakson erityiskäytänteistä.

Student workload

Yksi opintopiste vastaa 27 tunnin työmäärää. Yhteensä kurssi vaatii 54 tunnin työmäärän.

Assessment criteria, satisfactory (1)

Sufficient 1:
You have completed all measurements and completed all course assignments. There are shortcomings in the recording and reporting of measurement results. The conclusions of your report would be better if the measurements and their analysis were better performed.

Satisfactory 2:
You have completed all course assignments in terms of measurements and reporting. You have recorded the relevant data from the measurement results. Your reporting from the experimental work is limited, but it shows the right results. You have drawn some conclusions based on the data you have analyzed.

Assessment criteria, good (3)

Good 3:
In addition to the requirements for grade 2, you have recorded the measurement results correctly and have reported your work well. In reporting, you have presented the result in the correct format. You have made several different conclusions based on the measurements and data analysis.

Very good 4:
In addition to a grade of 3, you have made a comprehensive error estimate, in which the total error of the final result is calculated correctly using a statistical and a systematic error. In the conclusions, you have assessed the significance of the sources of error in the measurement method for the error of the final result.

Assessment criteria, excellent (5)

Excellent 5:
You have made an accurate measurement report showing the measuring devices used with their errors, the measurement data with systematic errors and a mention of possible faults. The level of the report you write is close to the level of the conference paper. In the conclusions, you have considered the error of the final result at least at the level of the grade 4. You have compared the result you have calculated with the benchmarks given in the literature.

Qualifications

Physical quantities and vectors, differential and integral calculus, SI system. The ability to use elementary functions and to solve groups of equations is needed in solving physical problems.

Further information

Arvioinnissa otetaan huomioon kurssipisteet kokeellisten töiden mittauksista (30 % arvosanasta), mittauksiin liittyvistä laskuharjoituksista (50 % arvosanasta) ja mittausryhmässä kirjoitetusta raportista (20 % arvosanasta). Kurssin läpäisyyn tarvitaan vähintään 50 % kurssin maksimipistemäästä ja mittausten tulee olla hyväksytysti suoritettuja.

Kurssin suorittaminen edellyttää läsnöoloa kahdella mittauskerralla, jotka määritetään kurssin ensimmäisellä viikolla. Jos opiskelija on estynyt osallistumasta mittauksiin, tulee kurssin opettajalle ilmoittaa kurssisuorituksen estymisestä ensimmäisen kurssiviikon aikana.
