Some Games You Finish. Others You Never Forget.
“When you play Sonic Pinball, you’re playing the future of pinball.”
— Joe
There are invisible forces impacting you in countless ways, every day, whether you believe in them or not. No, we’re not talking about secret societies or alien superintelligence, we’re talking about something much closer to home—in your game room, in fact.
Picture this: Two games, same genre, same graphics budget, same designer. One feels hollow. The other feels alive. The difference isn’t what you see — it’s what your body believes.
At Jersey Jack Pinball we've spent years chasing that feeling with every new pinball machine, and nothing has embodied it better than our latest machine: The Sonic The Hedgehog Pinball Pinball Machine. Here's why physics is the secret behind every legendary game — and why pinball has always been its purest expression.
Discover The Sonic The Hedgehog Pinball Machine
Article Overview
It’s not graphics or story that makes a game unforgettable — it’s whether the movement, weight, and momentum feel believable. When physics are off, players feel it even if they can’t name it (“floaty” is the word they reach for).
Sonic the Hedgehog was secretly a physics masterclass. Sonic’s genius wasn’t speed — it was momentum. Slope acceleration, loop retention, and rolling mechanics all mirror real physics principles.
Jersey Jack Pinball proves pinball is still one of the purest forms of physics-driven gaming ever created.
What Is Video Game Physics?
Video game physics is the simulation of real-world forces — gravity, momentum, friction, collision — except it’s all happening inside a game engine instead of the real world.
But here’s the thing: the best physics engines aren’t trying to perfectly recreate reality. They’re trying to recreate the feeling of reality. There’s a meaningful difference. A ball doesn’t need to behave with scientific precision — it needs to behave in a way that your body recognizes as true. When a game nails that, you feel it before your brain can explain it: the tension of a close call, the satisfaction of a perfect landing, the weight of something massive hitting the ground. That’s not just programming. That’s craft.
Pinball Built the Blueprint For Physics Before Computers Existed
Long before modern game engines were rendering explosions or calculating ragdoll physics, pinball machines were already doing something extraordinary: translating the laws of physics into one helluva entertaining ride. (Even if the entertainment bit was kinda accidental.)
Pinball wasn’t originally engineered to be fun. It was engineered to be physically accurate. Fun was the consequence, because (it turns out) the dance between accuracy and satisfaction is intoxicating. It’s also the founding principle behind every legendary game.
Remember: Pinball doesn’t simulate physics. It is physics. It’s one of the oldest physics engines in entertainment (with Bagatelle probably taking home the trophy for “oldest” in the game). In fact, pinball was one of the earliest physical games to be emulated digitally — Atari pulled it off in 1979. Even Pong was kinda pinball-esque.
Pinball physics break down like this: You’ve got a steel ball that reacts in real time, meaning even the tiniest change in angle, timing, or flipper position can make or break a shot. You’ve got gravity pulling the ball down the playfield, momentum carrying it through collisions and curves, and friction determining how energy bleeds off between contacts.
Physics is like rhythm or moonshine: you don’t have to understand how it works to feel it deep in your bones. When game developers in the 80s started chasing that feeling, they weren’t ushering in some new discipline. They were trying to capture what pinball had already proven: that people don’t have to major in physics to be majorly turned on by it.
Pinball physics even inspired a digital pinball revolution, most famously with Zen Studios Ltd.’s release of Zen Pinball: Rollercoaster in July, 2008. But first (round-about the early 90s), pinball physics would inspire essential aspects of a game featuring everyone’s favorite hedgehog-turned-hero, and honestly? Things would never be the same.
Let’s Go Fast: Sonic the Hedgehog Was Built Around Momentum
“No other pinball company in the world could pull this off.”
— Steve Ritchie, Game Designer
Everyone thinks Sonic is about speed. I mean, they don’t call him the Blue Blur for nothin’. But if we’re gonna talk physics, Sonic is actually about momentum — which is a whole lot more interesting.
Most platformers of the era treated movement simply: press a button, character moves. Stop pressing, character stops. Yuji Naka and the Sonic Team threw that out entirely. They engineered movement around acceleration, slope physics, rolling resistance, and velocity conservation — the same principles that determine what happens when a steel ball hits a ramp, curves through a loop, and comes flying out the other side in a pinball machine. In both cases, nothing moves in isolation. Every surface, angle, and collision influences what comes next.
Slope Acceleration = Gravity Converting Potential Energy Into Kinetic Energy
One of Sonic’s defining mechanics is how he gains speed while whizzing downhill. And it’s not just through clever animation or level-design trickery. Sonic’s lifelike downhill trajectory mirrors a real-world physics principle: that gravity converts potential energy into kinetic energy.
As Sonic descends a slope, gravity naturally increases his velocity, just like a steel ball accelerating down a pinball playfield. This creates realistic motion that players can feel, even if they never consciously think about the math happening underneath the hood.
Loop Retention = Conservation of Momentum
If Sonic takes a loop with enough velocity, he maintains contact and completes the rotation. If he enters too slowly, gravity wins, and he falls out. That mechanic mirrors the conservation-of-momentum principles seen in pinball ramps, tracks, and loops.
This was a massive leap forward for computer games at the time because it forced players to interact dynamically with movement instead of just memorizing button presses.
Rolling: Reduced Friction Coefficient Increasing Speed
When Sonic curls into a ball, the game reduces friction and lets momentum carry him farther and faster.
Again, this reflects true physics logic. Reduced friction coefficients allow physical objects to preserve energy and travel more efficiently across surfaces. In Sonic, rolling transforms movement from controlled running into a kinetic flow.
And it’s probably no coincidence that Sonic’s first spinoff game was Sonic Spinball. After all, Sonic did more than borrow pinball’s visual language. It utilized the same physics logic, which is why it felt revolutionary in 1991, and hasn’t lost an ounce of its appeal in 2026.
That philosophy helped shape Sonic’s success, sure, but it also shaped the future of immersive experiences in the gaming industry worldwide. Sonic sent a clear signal to game programmers everywhere: the games that understood physics-based momentum did more than make a splash.
They earned Legendary status.
The Games That Carried the Physics Torch
Pokemon Pinball
“The ball physics are best in class on the platform (above Kirby and Gator), so it’s most of the time predictable, and you can actually rely on skills to play the game instead of pure luck.”
— Redditor
The physics of Pokémon Pinball is oft-praised for rewarding skill and strategy over dumb luck. The ball behaved consistently, so players could steadily build mastery through precise aiming, intuitive tilt bounces, and advanced techniques like flipper passing. Every session was a chance to improve, not just hope for the best.
GTA IV (Euphoria Engine)
“Oh god yessssss! There is something in games with realistic (or cool) impact physics that makes me drool.”
— Redditor
Powered by the Euphoria Engine, GTA IV gave virtual bodies something games had struggled to fake for decades: mass. NPCs stumbled, braced for impact, tried to recover balance, and reacted dynamically to force. For the first time, players saw physics emerge from motion itself.
The Legend of Zelda: Breath of the Wild
“BOTW invites, challenges, and rewards the player for creative use of the interaction between objects in the world.”
— Redditor
The Legend of Zelda: Breath of the Wild built one of the most coherent physics playgrounds ever made. The fire has updrafts, the metal conducts electricity, and heavy objects carry momentum downhill. Plus, if you drop raw meat on Death Mountain, you’ve got instant steak. That might not be physics, but it is BBQ—and that’s worth at least an honorable mention.
So Why Do So Many Modern Games Feel... Off?
It’s not uncommon for gamers to gather together (online, usually) to ask a burning question: Why do so many modern games feel so… OFF? If you ask some people, there’s an unmistakable wrongness to certain games, and it violently ejects them (mentally, of course) from the very world they’re meant to be enthralled in. So, what gives?
Physics Dissonance Makes Things Feel Wrong
Physics dissonance is the disconnect you feel when something in a game moves in a way that contradicts how objects behave in real life. It’s why a character can look photorealistic and still feel completely wrong to control.
Players have a word for it: floaty. Hang out long enough on Reddit, Quora, or YouTube comment sections and you’ll see the same complaints surfacing over and over — characters feel weightless, cars slide more than they grip, movement looks realistic but feels fake. Sometimes players can’t even name what’s off. They just know something is.
You don’t have to be Isaac Newton to feel physics dissonance. You just need to have lived in a human body, which means most of us qualify. Our brains have spent a lifetime learning how weight, momentum, and gravity behave — and when a game violates those expectations, we feel it immediately, even if we can’t explain it.
The root cause is simple: as games chased graphical fidelity, investment in physics often dropped. A game can look stunning and feel completely hollow if the momentum system underneath is lazy.
But physics never went anywhere, and the best studios never abandoned them. Most importantly, there’s one medium that never compromised an inch, mostly because it couldn’t. A steel ball on a real playfield obeys real laws whether you want it to or not.

How do physics engines work in games?
A physics engine is the system inside game engines that handles motion, collision detection, and interactions between objects. It uses principles of classical mechanics to simulate physical phenomena like gravity, momentum, and impact. The goal is to create a responsive, consistent system that feels intuitive to the player.
What is ragdoll physics?
Ragdoll physics is a simulation that governs how characters or objects move after losing structured control (like when a character falls or gets knocked back). Instead of playing a fixed animation, the movement is dynamically calculated, creating more natural results.
How do game developers use physics to shape gameplay?
Through careful game physics engine development, game developers decide how responsive, weighty, or fast a game feels. Small changes to gravity, friction, or timing can completely change how players experience a game. This is where physics goes from a background system to a core design tool.
Why do some games feel more immersive than others?
A lot of the time, immersion comes down to consistency. When a game world aligns with your expectations (for example, through believable physics simulations and responsive interactions), it creates a seamless experience. When it doesn’t, the illusion breaks.
What are rigid bodies in video game physics?
In video game development, rigid bodies are physical objects that move and react according to simulated forces. Rigid-body dynamics help determine how objects collide, bounce, rotate, and transfer energy within a game environment.
Do video games use real physics?
Not exactly. Most computer games use simplified versions of Newtonian physics to recreate the feeling of reality rather than perfectly duplicate real life. Remember: The goal is usually responsiveness, satisfaction, and gameplay balance.
What makes physics-central games feel so satisfying?
Strong physics-based gameplay creates consistency. When momentum and movement behave the way your brain expects them to, you feel more connected to the game world. Even subtle details like the arc of a jump or the weight of a rolling object can dramatically affect how immersed you feel.
Why do momentum mechanics in games matter?
Momentum mechanics in games create a sense of physical continuity between player input and on-screen action. Games with believable acceleration and movement physics feel more responsive and rewarding because actions carry real force and consequence.
