Conclusion

A Slower Speed ​​of Light

PC, Mac and Linux - Free

Action about the perception of space at near-light speeds: the main character collects special spheres and observes the aberration of light, relativistic time dilation, Lorentz transformations and the Doppler effect. The game was developed by the Massachusetts Institute of Technology (MIT) Games Lab, which has been gamifying everything from education to political activism for more than five years. Slower Speed ​​of Light is a response to the requests of students who find it difficult to understand the special theory of relativity, since its effects cannot be seen in everyday life. The game is made with the OpenRelativity toolkit, which simulates relativistic effects on the screen. By the way, the "relativity" code is in the public domain on GitHub - anyone can use it if they wish.

Particulars

PC, Mac and Linux - $5 to $50 (free demo available)

“The loneliness of the bottom quark in subatomic space,” in a review of this game, The Guardian journalist admitted that he almost burst into tears. Particulars is an arcade and puzzle game mixed with particle physics. By controlling the bottom quark, the player interacts with other particles - they attract and repel, connect, collapse and change polarity according to physical laws. Particulars does not go into details, but you can understand the principles of the theory.

Crayon Physics Deluxe

PC, Mac and Linux - $19.95, Android and iOS - $2.99

Puzzle about the basics of mechanics - gravity, acceleration and friction. The player helps the ball to collect stars and draws bridges, crossings and levers on its way. Crayon Physics would be just another Goldberg machine game if it wasn't for the art: wax crayons, children's drawings, soft music in the background - the game looks like anything but the hardcore physics puzzle (which it is).

Algodoo

PC and Mac free, iOS $4.99

Two-dimensional simulator of mechanical objects. Algodoo's toolkit allows you to create very advanced mechanisms: you can even make a car out of simple blocks, gears, springs, chains and ropes. There is an analysis mode that shows what forces are acting on the site and how they interact with each other. Novice mechanics will be helped by dozens of training videos on YouTube and a section with blanks on the official website.

Powder Toy

Powder Toy looks very similar to Algodoo at first glance, but pays more attention to the pressure and temperature in the various vessels. And while Algodoo mechanics are building planes and ships, Powder Toy pyromaniacs are building nuclear reactors and volcanoes - and it's no easier.

Newton's Playground

iOS - $0.99

The application simulates the gravitational interaction of the planets. Dozens of spheres float across the screen and, falling into each other's orbits, change trajectories. In Newton's Playground, you can even build the solar system by experimenting with the mass and density of celestial bodies.

Tear-able Cloth

Web, free

The programmer Stuffit posted a Javascript code that simulates the physics of fabric. It can be pulled, torn, and generally changed properties. This requires making changes to the code - however, with due attention, even those who are unfamiliar with Javascript can do this. Experiments with gravity and density lead to the most interesting results: for example, partially cut tissue under the influence of gravity can begin to tear without your participation.

Vernier Video Physics

iOS - $4.99

The Vernier Video Physics app allows you to study everyday activities from a physics perspective, such as the behavior of a basketball when thrown. First, the user loads the video of interest to him and specifies the size of one of the objects in the frame, so that the application determines the coordinates of the space. Then he indicates the position of the object in different frames, drawing the trajectory of its movement. Based on the received data, Vernier will determine how and at what speed the position of the object in space changed.

iCircuit

PC - $4.99, Mac - $9.99, Android and iOS - $4.99, Windows Phone - $2.99

School physics lessons do not give proper scope for experiments with electrical circuits. The iCircuit app fixes things up and gives you access to an infinite number of resistors, tubes, rheostats and more. Some users even make simple synthesizers and electronic clocks.

Teachers can only choose, if, of course, they are ready for this choice. Today we bring to your attention 13 different applications and games that can come in handy when learning physics. However, they are so interesting that they are quite suitable not only for pupils and students, but also for everyone who is interested in the structure of our world.

Snapshots of the Universe is an amazing iOS app recently released by Stephen Hawking himself in collaboration with Random House. The application consists of eight experiments that give users the opportunity not only to gain basic knowledge of physics, but also to get acquainted with the principles that govern our universe. As part of the proposed experiments, players can send rockets into outer space, build their own star systems, search for and study black holes. Each experiment can be carried out countless times, changing the physical parameters and observing the emerging effects. To better understand the experiments, you can go to the explanation section of the results and watch the video. The app is available on iTunes. The cost of the game from the great physicist is only $4.99.

This is a game with a unique combination of arcade and puzzle features, set in the world of subatomic particles. By taking control of one of the quarks, you must negotiate with the fundamental forces of the universe. Other particles will attract and repel, connect and change polarity, the task of the unfortunate quark is not to lose control and avoid destruction. Throughout the game, the story of Alison, a young physicist with a difficult past, runs like a red thread. Her journey through the subatomic world flows through flashbacks and ultimately leads to amazing discoveries. The site provides a free demo version, for the full one you will have to pay from 5 to 50 dollars, depending on the features of your system.

The first-person game developed by the Games Lab (MIT) allows players to get acquainted with the perception of space at near-light speeds and understand the theory of relativity. The player's task is to move around the 3D space, collect spherical objects that slow down the speed of light by fixed values, which makes it possible to observe various visual effects of Einstein's theory.

The slower the radiation moves, the clearer some physical effects appear. By the 90th collected stone, the light will spread at walking speed, which will make you feel like the heroes of a surreal world. Among the phenomena that the hero can get acquainted with during the game are the Doppler effect (a change in the player’s movement, the wavelength of the light he registers, which leads to a change in the color of visible objects, which shifts to the ultraviolet and infrared region), light aberration (an increase in the brightness of light in the direction movement), relativistic time dilation (differences between the player's subjective sense of time and the passage of time in the outside world), Lorentz transformation (distortion of space at near-light speeds), etc.

Crayon Physics Deluxe is a 2D puzzle/sandbox game that lets players experience what it would be like if their drawings could turn into real physical objects. The player's task is to help the ball collect stars by drawing surfaces suitable for its movement - bridges, crossings, levers, etc. Everything takes place in the magical world of children's drawing, where the player's tools are wax crayons. At a minimum, the game develops artistic vision and creativity, as a maximum, it allows you to get acquainted with the basics of mechanics - gravity, acceleration and friction. There is a demo version available for testing on the site, the full version for PC, Mac and Linux can be purchased for $19.95, the apps for Android and iOS will cost $2.99.

However, for those who have just begun to study the movement of bodies and various physical forces, it will also be interesting to get acquainted with the educational video game Physics Playground. The game is a platform on which the player needs to perform fairly simple actions - using a green ball to shoot down a red balloon. This is where classical mechanics comes in: without the correct application of Newton's laws, players are unlikely to be able to construct mechanisms in an interactive environment that will help set the ball in motion. However, you can also use intuition - the main thing is that over 80 levels, intuitive knowledge that allows you to achieve your goal gradually leads to an understanding of the laws that underlie classical mechanics. The game was developed by the Empirical Game company, which is engaged in the creation of educational educational games. Unfortunately, it is not available in the public domain, but the developers suggest contacting them if you are interested in this product. In the full version, you can track the progress of players by analyzing the log file logs.

“Science, entertainment and gaming come together in Newton’s Playground’s beautiful, unique creative experience. Manipulate the universe, create incredible combinations of planets and run gravity, ”the creators of the application say. Newton's Playground is an interactive application based on models that reflect the gravitational relationship of various bodies. By simulating the gravitational relationships of the planets, the small app Newton's Playground gives its players the opportunity to observe the interaction of spheres floating in open space, or experiment with the mass and density of various bodies and create their own solar system. All calculations are based on research by the Sverre Aarseth's Institute of Astronomy. The cost of the application in the App Store is $1.99.

"Algodoo creates a new synergy between science and art," reads the inscription on one of the game's pages. Algodoo is a unique 2D physics simulation platform from Algoryx Simulation AB. With cartoon images and interactive tools, Algodoo allows you to create amazing inventions, develop games for use in the classroom or special experiments for physics labs. In the course of their natural tests and the creation of various mechanisms, the participants of the game can use liquids, springs, hinges, engines, light beams, various indicators, optics and lenses. By simulating various structures and changing parameters, players study friction, refraction, gravity, and so on. For beginners, the site provides a detailed guide, as well as a channel Youtube, where you can watch dozens of videos on the topic. Free versions of the game are available for Windows and Mac, and the iPad app costs $4.99.

Autodesk ForceEffect is an application for engineers who are engaged in various kinds of design. With Autodesk ForceEffect, you can do engineering calculations right on your mobile device. This greatly facilitates the design work at the concept stage, as it immediately determines the viability of the design. However, the application will also be of interest to those who would like to know how different forces affect objects. For such enthusiasts, instead of a house diagram for an experiment, you can take an ordinary bicycle and, based on its photo, conduct a series of experiments that will show how much load it can withstand and what affects the balance of the bike. It is especially pleasant that the application is in the public domain and is available for free for Android, iOS.

And now let me introduce the members of the jury: (introduction of the members of the jury. These can be teachers and colleagues invited in advance or high school students). So, we begin. And the first contest - Greetings. Each team was given homework: come up with a team name, draw an emblem on A4 sheet, come up with a motto - a quatrain. This competition will be evaluated with a maximum score of five points. Captains, I ask you to come forward (introduction of captains). The draw will determine which team will play first. (carrying out a draw)
1 team is invited to the department. (performance of 1 team). Let's applaud the speakers. Take your seats. And we ask you to show your greetings to the 2nd team (performance of the 2nd team, applause).
Members of the jury, there are tables for evaluation in front of you, I ask you to enter your marks for the "Greeting" contest.
And we continue. 2 contest "Understand me". Rules of the competition: 2 people from the team are invited to the department. They receive 5 cards each. Each card has one word or phrase that represents a physical term. The player must explain this term to the team with any non-single-root words in order to guess it. If it is not clear how to explain this word, then it can be removed to the end of the stack and explained at the end if there is time. Each player is given 50 seconds. One guessed word - 1 point.
So, 2 people from 2 teams are invited. (Holding a competition, summing up the results: how many words were guessed). And now we ask the guys from the 1st team to the board. (Holding a competition, summing up the results: how many words were guessed). Dear jury members, do not forget to enter the results in your tables.
(Terms for the competition in Appendix No. 1)
The next stage of our game called "Formula 1": a formula is displayed on the screen, a student from the team says its name, the correct answer is displayed on the screen. 1 person - one formula. One correct answer - one point. So we ask team 1 to line up in a column one at a time in front of the screen. Jury members please be careful. In case of a hint, one penalty point is removed from the team. We started (the teacher clicks the pages of the slide presentation with the mouse, the guys guess the name of the formula one by one and sit down in their place).
Excellent, 1 team earned ... .. points. We ask the second team to line up in front of the board in a column one at a time. We started (the teacher clicks the pages of the slide presentation with the mouse, the guys guess the name of the formula one by one and sit down in their place). So, the 2nd team earned ... .. points.
And now let's move on to the very, very practical competition "creators of myths." On the desk for each team there is equipment for physical experience. Nearby are cards with tasks for which you need to enter answers in the course of practical work. Each correct answer is 1 point. The maximum score for this competition is 5 points. Three people are invited from each team. 5 minutes are allotted for the competition. So the time has come. (the guys are conducting an experiment, the teacher monitors the implementation of safety precautions, keeps track of time. The jury members have an answer sheet for this competition.) ... Time is up. Teams are requested to submit their answer sheets to the jury for summing up.
And the last competition is the competition of captains "Physically strong". Captains are invited to the board.
The conditions of the competition are as follows: within 1 minute I give the captains the name of the value - in response, they must name its unit of measurement in the "SI" system. If I tell them a unit of measurement, then in response they should name a physical quantity. Each correct answer is 1 point. (in this competition, all the quantities studied by students in grade 7 are called.)
