Title: Zbirka zadataka iz fizike za 2 razred gimnazije Author: Ahmed Čolić Target Audience: 2nd-grade high school students (Gymnasium/General Education) in Bosnia and Herzegovina and the region.
"Zbirka zadataka iz fizike za 2 razred gimnazije" by Ahmed Čolić is considered a standard and reliable resource in the regional educational system. It serves as a practical tool for students aiming to master the fundamentals of electricity and waves. For teachers, it provides a robust bank of assessment questions. While it may lack modern visual flair, its substance and alignment with the curriculum make it a highly recommended text for serious physics students.
Ahmed Colić držao je knjigu u rukama dok je kišna večer tiho padala preko grada. Naslovnica, jednostavna i dobro poznata: Zbirka zadataka iz fizike za 2. razred gimnazije. Stranice su mirisale na mastilo i papir, nosile su tragove ranijih ruku — podvlačenja, sitnih bilješki na marginama, jedna stara hemijska olovka zaglavila između listova kao da čuva tajnu.
Ahmed je bio učenik koji je voli prelaziti granice običnog. Dok su njegovi drugovi brojali minute do kraja časa, on je za sobom nosio znatiželju koja nije posustajala. Fizika mu je bila više od zadataka: bila je način da razume kako se svet pomera, kako svetlost prelazi staklo, kako se talasi šire i kako male sile grade velike promene.
Te večeri, svetla u sobi su mu bacala senke preko stranica zbirke. Otvorio je prvo poglavlje — mehanika — i odmah naleteo na zadatak koji je vekovima plašio đake: sistem kosih ravni sa kočnicom i trenjem. Ali Ahmed je video drugačije. Umesto da računa samo komponente sila, zamislio je klackalicu između dve planete. Ravnina je postala most, telo na njemu brod koji pokušava da se uzdigne protiv nevidljive oluje. Računi su se nizali, ali svaki korak je bio priča: energija koja prelazi oblik, rad koji hrani kretanje, trenje koje šapuće upozorenje.
Na sledećim stranama pojavio se zadatak o talasima. Ahmed nije mogao da odoli da ne pretvori matematičku funkciju u muziku. Sinusni talas postao je zvučni val koji putuje kroz staklo prozora, donoseći iskričave fragmente kiše. On je zamislio sopstveni orkestar od molekula koji su udarali jedan o drugi i stvarali harmonije, a formule su bile notni zapisi.
Kad je naišao na poglavlje o elektriciturtu i magnetizmu, podigao je pogled prema kompjuteru na stolu. Električni krug je u njegovoj mašti postao mreža gradskih ulica, struja automobili koji žure ka raskrsnicama. Otpor je semafor koji usporava saobraćaj; kondenzator je garaža gde se energija čuva; induktor tajanstveni skretničar koji čuva trenutke sećanja. Ahmed je crtajući dijagrame, crtao i mapu grada koji je mogao da zaživi pod pravilima fizike.
Kroz zbirku je prolazio kao kroz šetaliste domena — svaki zadatak otvarao je drugačiju scenu, drugi izazov. Nije ga zanimala samo tačna cifra na kraju; tražio je priču koja objašnjava zašto je rezultat takav. Ponekad bi zastao nad teoremskim izvodima, pa bi ih pročitao naglas, kao da izgovaranje reči pomaže da zakoni prirode počnu da šapuću svoje tajne.
Jedne noći, dok je računao zadatak o sudaru dve čestice, kucnjava na vratima ga je prekinula. Na pragu je stajao njegov profesor fizike, stariji čovek s blagim osmehom, koji je znao Ahmedovu strast. "Šta tamo radiš tako duboko u formuli?" upitao je.
Ahmed je pokazao na zbirku. "Vidim priče. Ne samo zadatke."
Profesor se nasmejao i seo za sto. "Znaš, svaka dobra zbirka zadataka krije nešto više od brojeva. Ona uči kako misliti. Kako pretvarati apstraktno u konkretno."
Zajedno su otvorili jednu od teških vežbi i počeli da razgovaraju o različitim pristupima. Profesor nije samo ispravljao greške — on je davao perspektivu, pokazivao gde se jedan način razmišljanja može primeniti na drugi problem. Ahmed je upijao, zapisivao marginalije koje su postajale njegovim novim tragovima.
Vremenom su stranice zbirke postale mapa njegovog napretka. Svaka izvučena linija, svaki izračunati broj, svaka skica — sve su to bili kamenčići na putu stvaranja razumevanja. Ahmed je osećao kako se njegova radoznalost pretvara u sposobnost: iz formula je izvlačio intuicije koje su mogle opisati svet van učionice — gibanje ljuljaški u parku, odziv mosta na vetar, bljesak dalekih zvezda.
Na kraju školske godine, kada su zadaci iz zbirke postali lakši, Ahmed je shvatio koliko je napredovao. Zbirka nije više bila samo knjiga zadataka; bila je svedočanstvo jednog puta — putovanja kroz nepoznato gde je svaki zadatak bio stub, svaka rešenost deo mosta koji ga je odveo dalje.
I dok je zatvarao korice, u glavi mu se pojavio novi naslov — ne fizički, već obećanje: napisati svoju zbirku priča o fizici, zadatke koji će drugima pomoći da pronađu svoje mostove i orkestre, svoje gradove i priče skrivene u formulama. Kiša je prestala; u tišini koja je usledila, glasovi zakona prirode delovali su manje zastrašujuće, više pozivajući. Ahmed je znao da je to tek početak. ahmed colic zbirka zadataka iz fizike za 2 razred gimnazije
In the quiet, dust-mote-filled library of the Sarajevo Second Gymnasium, the blue-covered book didn't just sit on the shelf; it loomed. To most, it was simply Ahmed Čolić: Zbirka zadataka iz fizike za 2. razred. To the students, it was "The Blue Bible of Suffering."
Sead stared at Problem 4.12. It was a classic Čolić curveball: a block on an inclined plane, but with a pulley system so complex it looked like a spider had a stroke while spinning it. Sead’s pencil tip snapped. He had been staring at the same diagram for forty minutes.
Legend had it that if you solved every problem in the Čolić collection without looking at the solutions in the back, you didn’t just get an 'A'—you actually started to see the world in vectors. You’d see the force of friction acting on a sliding coffee cup; you’d calculate the centripetal acceleration of a tram turning at Skenderija before it even moved. "You’re overthinking the tension," a voice whispered.
Sead looked up. It was Amina, the girl who could derive Maxwell’s equations while eating a pita. She tapped the page. "Čolić isn't testing your math here. He’s testing your patience. Look at the angle again."
Sead looked. He’d been treating the incline as 30 degrees, but a tiny, almost invisible footnote indicated a change in the coefficient of friction halfway down. It was a trap. A classic Ahmed Čolić "gotcha."
They worked in silence for three hours, the scratch of graphite against paper the only sound. By the time the sun began to set over the Miljacka river, the blue book was filled with sticky notes. Sead felt a strange sense of clarity. The chaos of the physical world—the falling rain, the hum of the heater—suddenly felt like a series of solvable equations.
As they packed up, Sead looked at the weathered cover of the book. It was frayed at the edges, passed down through generations of students who had all cursed Čolić’s name under their breath.
"Do you think he actually expects us to finish it?" Sead asked.
Amina smiled, tucking the book into her bag. "No. I think he just wants us to realize that the world is complicated, but if you break it down into enough components, nothing is truly impossible."
Sead walked home that night, subconsciously calculating the parabolic trajectory of a tossed cigarette butt, and for the first time, he wasn't afraid of the physics final. He had the Blue Bible on his side.

This is a comprehensive guide to using Ahmed Čolić’s Zbirka zadataka iz fizike za 2. razred gimnazije (Collection of Physics Problems for 2nd Grade of Gymnasium – typically ages 15–16). The book is a standard in Bosnia and Herzegovina, Serbia, Croatia, and Montenegro, covering mechanics, thermodynamics, and oscillations.
Over the years, countless students have reported that the problems on their final exams were almost identical to those in Ahmed Čolić’s zbirka. Teachers often draw inspiration—or directly use—problems from this collection. One student from Sarajevo shared:
“I failed physics in the first semester. Then my tutor gave me Čolić’s zbirka. I did every problem in thermodynamics and optics. By the second semester, I had a 4 (out of 5). This book saved my grade.”
Another student from Novi Sad noted:
“The key is the ‘mixed problems’ at the end of each chapter. Those are exactly like the real exam.”
Due to its popularity, the book is often sold out in local bookstores (knjižare). Here are your best options:
Common symbols you’ll see:
| Mistake | Why it happens | Fix | |---------|----------------|-----| | Using (g=9.81) when answer requires (10) | Not checking the back-of-book answer’s roundness | Try both. If answer is a clean 20, they used 10. | | Forgetting to convert cm to m | Pressure problems often list (h) in cm | Write (h=0.05,m) immediately | | Wrong sign in work-energy | Confusing work done on vs by system | Work done BY system = + when expanding | | Adding vectors incorrectly | Skipping the drawing | Always draw head-to-tail | | Using (T) in °C in (pV=nRT) | Memory lapse | Write “(T(K)=T(C)+273)” on a sticky note on the book cover | | Assuming friction = (\mu N) is always kinetic | Not checking if object is moving | If object isn’t sliding, use static friction (\mu_s) with inequality (F_push \le \mu_s N) | | Misreading “horizontal force” as slanted | Not carefully reading | Circle every adjective (“horizontal”, “vertical”, “smooth”) |
As the test approaches, select 5–10 mixed-difficulty problems and solve them in 45 minutes (typical class period). This simulates real exam conditions.
Key formulas you must memorize:
Common problem types in Čolić:
Typical mistake: Forgetting to split motion into segments (reaction phase vs braking phase).
Example from zbirka (paraphrased):
“A stone is dropped from a bridge and hits water after 2.5 s. Find height of bridge.”
Solution: ( h = \frac12 g t^2 = 0.5 * 9.81 * (2.5)^2 = 30.66 , m ).
If back-of-book says ~31 m, correct.
