Beyond the Textbook: How Physics Works in Our Daily Lives (and in Your Games!)

 

Have you ever wondered how physics works? It's not just about dusty textbooks and complex equations. The truth is, physics is the hidden engine behind everything we do, from the mundane to the magnificent. From the moment you wake up to the moment you go to bed, you are a living, breathing testament to the laws of physics.

How Physics is Used in Everyday Life

Think about something as simple as throwing a ball. The trajectory it follows—the arc it makes through the air—is governed by gravity and air resistance. That's physics in action. When you drive a car, the friction of the tires on the road, the force of the engine, and the car's momentum are all dictated by physical principles. Even something like cooking involves physics; the transfer of heat, the way liquids boil, and how a microwave works are all examples.

So, what physics concepts are involved in walking or running? It’s a complex dance of forces. When you walk, you push off the ground, and the ground pushes back (Newton's Third Law!). Your body's center of gravity shifts, and momentum propels you forward. In sports, how physics is used in sports is a huge topic—from the spin on a football to the aerodynamics of a cyclist's helmet.

From the Real World to the Virtual World: A Seamless Transition

But what if you're not a scientist or an athlete? What if you're a creator, a developer, or someone who loves building worlds? You might be asking, "How do physics engines work?"

This is where the real magic happens. A physics engine is a piece of software that simulates physical interactions in a virtual environment. It takes all those real-world laws—gravity, friction, momentum, and collisions—and applies them to the digital objects you create. For a game developer, this is what brings a world to life. It's why a character falls realistically after a jump, why a stack of blocks tumbles authentically, and why a car doesn't just pass through a wall.

This is the bridge between the physics we see every day and the physics that powers our favorite video games. It’s the answer to "Can physics be different in other galaxies?" when you're the one in control, defining the gravity and forces of your own unique universe.

The Unity and C# Connection

For anyone looking to create realistic, engaging games, understanding these principles is key. The Unity game engine, combined with the power of C#, provides a robust platform for implementing these physics laws. It’s a direct application of real-world physics concepts to solve creative problems. You get to be the architect of a world where gravity can be weaker, a character can jump higher, or a car can drift with just the right amount of friction.

If you're ready to bridge the gap between abstract physics concepts and practical game development, you're in the right place. My book, "Physics for Unity and C#," is your guide to mastering these principles. It's designed to show you how physics works in the virtual world, giving you the tools to build your own immersive and believable game environments.

Unity 6 Physics Optimization: How to Fix Lag and Jitter in Your Games (2025 Guide)

  If you’ve ever hit Play in Unity, only to watch your beautifully crafted scene grind to a stuttering mess when physics objects start colliding—don’t worry, you’re not alone. Physics is one of the most powerful features of the Unity engine, but if not optimized properly, it can tank performance and break immersion. The good news? With Unity 6’s updated physics tools, you have more control than ever to reduce lag, fix jitter, and make your games feel silky smooth. In this guide, I’ll walk you through the must-know physics optimization tricks —and show you how to avoid the mistakes that kill performance in 2025. Why Physics Optimization Matters in Unity Game physics isn’t just about falling cubes or bouncing balls—it powers player movement, collisions, projectiles, vehicles, and even ragdolls. But physics calculations are expensive. Every rigidbody, collider, and force adds to the workload your CPU has to solve every frame . If you don’t optimize physics: Fast-moving objec...

ClickFunnels Alternative that can Clone your funnels and Host it on your Dedicated Server

There is no doubt that ClickFunnels is a good sales funnel builder and it is recommended by many marketers and salespeople. The issue here is that it gets really expensive to use over time and it becomes hard to maintain the fee especially if you are not making much money. To top this, you can not move your already built funnels away from ClickFunnels into another platform. It is just impossible, so you are literally cages or imprisoned into ClickFunnels. Once you are in, there is no way out. Good news, in this article I will show you a tool or let me say a secret way to move all your funnels away from Clickfunnels and host it anywhere you want. But it will cost you a little dollar, just $27 per month or $67 per year depending on what subscription you take. In just a moment, I will reveal to you the ClickFunnels Alternative that can help you a clone and move your funnels from Clickfunnels and host on your server. It also gives you more features and benefits that are just perfect for yo...
