About Newton's Fourth Law

Why can’t we learn physics in the same way we learn games?

Explore the laws of physics like never before in Newton's Fourth Law, where each puzzle is a lesson and every level deepens your understanding of the universe. From projectile motion to quantum physics, Dive into hands-on challenges that bring physics equations to life, inspired by classics like Portal and The Stanley Parable. But who exactly are you and what are you doing in this facility? Who is the mysterious voice guiding and chastising you?  Learn the rules of our universe, then uncover the mystery that is breaking them. Developed by a passionate high school physics teacher, this game challenges you to solve problems using real scientific methods.
Forget about educational science simulations that look like they were made before the internet. It's time to level up how we learn.Visualize key physics concepts!Inspect Your Surroundings to gather Information.
Master progressively more difficult physics puzzles using real world physics concepts and equations.
Experience physics in a completely new immersive way.
Uncover the intertwined destinies of Dorian, the luckiest man who ever lived, and Sheryll, a scientist who confronts the secrets of The Institute, and piece together your role in this expansive galaxy spanning sci-fi story.
Question everything.

We have to do actual calculations in this game?


Yes!As a high school physics teacher who loves video games, I always wished somebody could create a game that captures the wonder of videogames with the educational rigor of a real science class. So, I made it myself.
If you are studying physics in school or college, or just have an interest in physics and some of the deeper questions that science evokes, then this is the game for you.

This looks too hard for me!


I want to make this game accessible for everybody to learn physics. The game contains plenty of environmental cues to help guide you, as well as a hint system if you get stuck.Don’t worry—Newton’s Fourth Law is designed to make physics accessible. With built-in visualizations and a  hint system. The puzzles in this game are designed around a high school physics syllabus, including AP, IB, A-levels and other national curricula and currently cover the following topics:
  • Linear motion
  • Projectile motion
  • Forces
  • Energy
  • Collisions
  • Circular motion
Join us in shaping the future of Newton's Fourth Law! Early Access players will help expand our physics universe, with new levels and topics added regularly.
  • Thermal Physics
  • Waves
  • Fields
  • Electricity
  • Relativity
  • Quantum Physics

Don't be fooled: [b]the many positive evaluations are biaised, they don't evaluate the game but how physics enthusiasts feel for the game[/b]. Unfortunately, that gives a false idea about what the game is. 1. this is not about leanring physics, it's a physics exam. If you don't already know physics, you won't pass the tutorial, 2. solving these puzzles is about trial and error and guessing (and...actually, that's precisely pretty much like how real life public school logic works, so, goal? lol), 3. many solutions are theoretical only, and makes no sense in a practical settings, the game intself being a practical setting, it's pretty confusing, misleading. For example: the first puzzle of the game is in the third room (the first two rooms are useless to explain things). There, you have to apply a velocity to a cube so that the fast movement of a conveyonr belt underneath it slowly makes it slide and fall exactly on the right place. Except that: - the cube is not already moving, and there is nothing that can logically apply that velocity when we validate our input, - the cub stands on a platform that doesn't seem slipery and is not said to be slipery, so you can't tell that the c…

I really admire the effort put into the game and I appreciate how the developer kept us thinking and questioning about the limitation of our current physics framework. For me personally, it serves as a great reminder that physics is fun. I'm also looking forward to more stories about Dorian and Sheryll!

This game was so fun to play as a physics fan. The sentances at the beginning of each level added depth to the whole experience. I really hope the game will get more updates

Newton's Fourth Law is an ambitious and thoughtfully designed game that sets out to do something few titles genuinely attempt: teach real physics concepts through meaningful interaction rather than abstraction or trivia. Developed and published by Newtonian Studios, the game positions itself at the intersection of puzzle adventure and educational software, but it leans much closer to a full-fledged game than a digital textbook. From the outset, it makes clear that understanding physical laws is not optional background flavor but the primary tool players must use to progress. The setting is a mysterious, high-tech research facility where players are guided through a series of increasingly complex challenges tied directly to classical mechanics. Rather than presenting physics as a list of formulas to memorize, the game embeds these concepts into environmental puzzles that require genuine comprehension. Forces, momentum, energy conservation, projectile motion, and circular motion are not just referenced but actively applied. Each problem asks players to observe a situation, interpret what physical principles are at play, and calculate or reason their way to a solution. This approach …

i wouldn't have called it a game, but more like a physics class. still, i enjoy it. i hope there can be more game parts, like an interactive class. to be a real game, one should be able to complete this game with minimum physics knowledge, and start from scratches. else, the calculation part can be of something larger, like an adventure game that requires you modifying the 3D vector of velocity to make character move. doing so would have been a completely different game, but that's a real game.

As if I were in middle school classrooms again, but the problems I was working on all came to life.
