Gentz, Fysiikan perustiedot. Harjoitustehtävien ratkaisut A - Basic knowledge of physics. Solutions to exercises A

1. Opetellaan tai kerrataan aihealue teoriasta.
2. Yritetään ratkaista aihealueen harjoitustehtäviä.
3. Verrataan ratkaisua annettuun ratkaisuun ja katsotaan mallia ratkaistusta tehtävästä.
4. Kun mielestään jo osaa, voi yrittää ratkaista tehtäviä, joihin annetaan vain vastaus.

Opiskeluun tarvitaan kolme osaa: teoriaosa, harjoitusesimerkit ja ratkaisut. Koska nämä ovat eri kirjoina, niitä on kätevä käyttää: kätevämpää kuin selata ”läppärin” pienellä kuvaruudulla. Suosittelen laskujen laskemista kynällä vihkoon. Pääaihealueet OSA I A Suure, Uuden fysiikan synnyttäminen, Kinematiikkaa, Fysiikan tehtävän ratkaiseminen, Dynamiikkaa, Työ, teho, energia, Käyräviivaisen liikkeen kinematiikkaa, Heittoliike, Nesteiden statiikkaa, Nesteiden ja kaasujen dynamiikkaa, Lämpöoppia OSA I B Lämpöenergia, Aineen kimmoisuus, Statiikka, Impulssi ja liikemäärä, Jäykän kappaleen kinematiikka ja dynamiikka, Gravitaatio, Painopiste OSA II A Värähdysliike, Aaltoliike, Geometrinen optiikka, Fotometria, Äänioppi OSA II B Sähköstatiikka, Sähködynamiikka, Magneettisuus, Sähkövirran synnyttämä magneettikenttä, Aineiden magneettisuudesta, Sähkömagneettinen induktio, Vaihtovirta OSA III A Sähkömagneettiset värähtelyt ja aallot, Atomifysiikka, Puolijohteista, Elektroniputkista, Ydinfysiikka OSA III B Hiukkasfysiikkaa, Suhteellisuusteoriaa, Tähtitiedettä, Työselostusohjeita fysiikan laboratoriotöihin, Antureista, Kolme mallityöselostusta (mittausohje, työselostus ja mittausliite) HARJOITUSTEHTÄVÄT 442 harjoitustehtävää, joiden yksityiskohtainen ratkaisu esitetään Harjoitustehtävien ratkaisut -kirjoissa. Lisäksi on 274 harjoitustehtävää, joihin annetaan vain vastaus. HARJOITUSTEHTÄVIEN RATKAISUT A Osan I (A ja B) kynällä kirjoitetut harjoitustehtävien ratkaisut. Esitetty myös erilaisia ratkaisutapoja. HARJOITUSTEHTÄVIEN RATKAISUT B Osien II ja III (A ja B) kynällä kirjoitetut harjoitustehtävien ratkaisut. Esitetty myös erilaisia ratkaisutapoja. HENKILÖHISTORIA 121 fyysikon ja kirjasarjassa mainitun tutkijan lyhyt elämäkerta. INTRODUCTION TO THE BOOK SERIES IN ENGLISH Basic knowledge of physics is suitable for a high school student who plans to study engineering or for a Master's degree in engineering or to study physics or medicine at university or in the Defence Forces, and for any students who are starting studies at the mentioned educational locations. On the left-hand side of book is the text in Finnish and on the right-hand side is the text in English. At the same time, Finnish-speakers learns English and English-speakers learns Finnish to cover: the central vocabulary of physics. The Finnish text has been read by a physics lecturer and principal lecturer. A linguist reviewer has revised the English part. The book series has 10 books, and each language to give a total of more than 2200 pages. The subject areas are partly familiar from high school physics. The requirement level starts at the high school physics level and is extended to the engineering physics level. Engineering students also have different study plans along different lines. The marking * refers to content at high school level, but not taught in high school physics. Since the curriculum is being changed, the star marking may not be in accordance with the current curriculum. The marking ** indicates an engineering level: differential and integral calculus and differential equations are needed to present the theory. Not everything presented is taught in engineering studies. In the practice exercises * marks an exercise that is more demanding, and ** marks exercises, where integral calculation is required. After the basic courses, the university has special courses in different areas of physics. They go deeper into physics than this book series. The book series is useful for studying basic courses. I named the book series Basic Knowledge of Physics, because during my teacher career I have taught everything else from this book series, except more narrowly particle physics. From a physics point of view, it misses some aspects, but they were not taught in the educational institutions where I taught during my teaching career. On the other hand, it presents the theory of physics, which nowadays is no longer taught in these educational institutions. These are information books, not textbook for any particular educational institution. The books can be used to studying high school and university of applied science physics courses (along different lines) as well as cadet physics courses studied in the Defence Forces. The book series is also useful in working life. Manual

1. Let's learn or repeat the subject area from theory.
2. Let's try to solve the practice exercises in the subject areas.
3. Let's compare the solution to the given solution and look at a model of the solved exercise.
4. When you think you already know, you can try to solve exercise for with only the answer is given.

Three parts are needed for studying: Theory, Exercises and Solutions. Since these are different books, it is more convenient to use them than browsing on the small screen of a “laptop”. I recommend calculating the tasks using a pen and notebook. Main subject areas PART I A Quantity, The rise of new physics, Kinematics, Dynamics, Work, power, energy, The kinematics of curvilinear motion, Mechanics of liquids and gases statistic of liquids, Dynamics of liquids and gases, About thermodynamics PART I B Thermal energy, Elasticity of materials, Statistics, Impulse and momentum, Kinematics of a rigid body, Dynamics of a rigid body, Gravitation, Centre of mass PART II A Oscillation, Wave motion, Geometric optics, Photometry, Acoustics PART II B Static electricity, a.k.a. electrostatics, About electrodynamics, Magnetism, A magnetic field caused by an electric current, Alternating current PART III A Electromagnetic oscillation and waves, Atomic physics, About semiconductors, About electron tubes, About nuclear physics PART III B Particle physics, Theory of relativity, About astronomy, Laboratory work exercises instructions for physics laboratory, About sensors, Three model work reports (work instruction, work report and measurement-related attachment) EXERCISES 442 exercises for which detailed solutions are presented in the Exercise Solutions books. In addition, there are 274 exercises for which only the answer is given. SOLUTIONS TO EXERCISES A Solution to the exercises written in handwriting in Part I (A and B). Various solutions are also presented. SOLUTIONS TO EXERCISES B Solution to the exercises written in handwriting in Parts II and III (A and B). Various solutions are also presented. HISTORY AND PERSONALITIES Short biographies of 121 physicists and researchers mentioned in the book series.
