Con­grat­u­la­tions to the final­ists and see you at the final stage!

Dear par­ti­cipants, the pre­lim­in­ary res­ults of the qual­i­fy­ing stage have been pub­lished. The res­ults can be viewed in your per­son­al account.

in case of tech­nic­al errors or ques­tions about the eval­u­ation cri­ter­ia, please send an email isys@​formulo.​org . Requests are accep­ted until Decem­ber 26, 2025.

The sub­ject of the let­ter is «Appeal.Physics».

In the text, you must spe­cify the par­ti­cipant’s full name, class, and explain what you dis­agree with.

Please note that the task for which you are appeal­ing is being rechecked, not the entire work.

Answers to task 11.1 must be entered sep­ar­ated by semicolons.
That is, if you have answers 1 and 2, you should write them in the format «1;2.»
Be sure to main­tain the order.

Here is the qual­i­fy­ing (remote) round of the competition.

We will be happy if your friends who like phys­ics also par­ti­cip­ate. How­ever, every assign­ment should be done indi­vidu­ally; oth­er­wise, your sub­mis­sion will not be considered.

Rules of the Olympiad

Dear par­ti­cipants!
Please read the rules of the Olympi­ad to avoid errors in writ­ing your answers:

1. The first round of the Olympi­ad is remote, and answers are checked auto­mat­ic­ally. A spe­cial pro­gram checks your answer against the cor­rect answer provided by the organ­izers. There­fore, to avoid pos­sible mis­un­der­stand­ings, please read the instruc­tions care­fully and fol­low them. Any appeals for fail­ure to fol­low the instruc­tions will not be considered.
2. All prob­lems require an answer in the form of a num­ber or sev­er­al num­bers, each with its own cor­res­pond­ing field. Be care­ful not to con­fuse the answer fields. If you enter the cor­rect answers in the wrong fields, the pro­gram will not accept them.
3. Please enter answers only as decim­al frac­tions: XX, XXX… Use a comma (,) as a separator.
4. Do not (are pro­hib­ited) include units of meas­ure­ment, for­mu­las, or any words in your answer. 5. If the prob­lem state­ment does not spe­cify the units to use for the answer, use SI units: meters, kilo­grams, seconds, etc.
6. Since all meas­ure­ments and cal­cu­la­tions in phys­ics are approx­im­ate, all answers must be giv­en with the cor­rect num­ber of sig­ni­fic­ant digits. For the rules for approx­im­ate cal­cu­la­tions, see the file «Rules for Approx­im­ate Cal­cu­la­tions.» If zer­os appear after the required num­ber of sig­ni­fic­ant digits in an integer, this will not be con­sidered an error. Writ­ing the num­ber 34.0 (3 sig­ni­fic­ant digits) as 34 will be con­sidered an error.
7. Sub­mis­sions sub­mit­ted after the dead­line will not be considered.

How to sub­mit solutions

To par­ti­cip­ate in the «For­mula of Unity» / «Third Mil­len­ni­um» 2025/26 phys­ics olympi­ad, it is neces­sary to sub­mit solu­tion by the dead­line of 23:59:59 UTC on Novem­ber 29, 2025. Please register in our inform­a­tion sys­tem and sub­mit your solu­tions through the per­son­al account. Import­ant: if you already have an account, there is no need to cre­ate a new one.

Be sure to read the par­ti­cip­a­tion instructions.

• Inform­a­tion system 
• Par­ti­cip­a­tion Instructions
