# Competition

Physics Náboj is an international physics competition designed for teams of five high-school students that represent their schools. The competition lasts 120 minutes during which the teams are trying to solve as many given problems as possible.

At the beginning of the competition each team receives eight problems. As soon as the team correctly solves any of the problems, it receives a new one. The solutions of the problems are usually numerical. The team that solves most problems correctly in the given time limit wins.

A more detailed description of the competition can be found in the section rules.

# About the problems

Difficulty of the problems is appropriate both for students inexperienced in physics competitions and for students who have already succeeded in Physics Olympiad or seminars. This is achieved by arranging the problems in order of their perceived difficulty. Problems in Náboj differ considerably from the routine school exercises which usually require only direct application of a given method: the Náboj problems require certain amount of inventiveness and ingenuity. Success in the competition does not depend on the individual abilities of the team members only but also on their efficient cooperation. Apart from enhancing imagination and logical reasoning our goal is to attract people to the endless beauty hidden in physics.

The professional quality of the problems is guaranteed by the organizers of Physics Correspondence Seminar part of Trojsten.

# Categories

Teams compete in two categories, Juniors and Seniors. The Junior category is open only for teams with all members attending first or second grade of a 4-year high school (or a corresponding grade in 5- or 8-year high school). The Senior category is open to any team consisting of high school students.

# Team fee

Participation in Physics Náboj is for free in all countries!

# Prizes

The best teams will receive certificates and prizes. Prizes usually include first-class physics literature (used worldwide for preparation for studying physics), electronics, or board games.
