“Serious Physics: Play This Silly Game to Learn”

This equation is known as the gravitational force equation, and it is used to calculate the gravitational force between two objects. In summary, the game of What If? 2 is a fun way to explore the serious physics of orbital motion. By playing the game, you can learn about the effects of gravity, the gravitational force equation, and how to get an object into a stable orbit. The game also serves as a great introduction to the concepts of Newton’s cannonball and the International Space Station.

I’m a huge fan of online games that don’t have a score or even a goal. One such game is a cartoon space simulator to promote the book What If? 2, by Randall Munroe, the author of the xkcd comics. You can play it by clicking here. (Don’t worry, I’ll wait.)

The Game for Serious Physics

Serious Physics

The game works like this: You start off with a rocket on a very small planet. Click on the rocket to start, then you can use the arrows on your keyboard to turn on the thruster, rotate the spacecraft, and find other planets and a few fun things that are mostly inside What If jokes. That’s it. That’s the game. It’s silly and fun, and I love it.

But it turns out that you can use even a simple game to explore some key concepts in physics. One of the things you can see on the initial planet is a recreation of “Newton’s cannonball”—Isaac Newton’s thought experiment about the connection between a fast-moving projectile and orbital motion. Newton said that if you were able to shoot a very fast cannonball horizontally off a very tall mountain, it’s possible that the curve of its trajectory could match the curvature of the Earth. This would make the cannonball fall but never hit the ground. (This is essentially what happens with an orbiting object like the International Space Station), only the ISS wasn’t shot off a tall mountain.

Seeing Newton’s cannonball made me assume that I could get my spacecraft to orbit this tiny planet, which would be fun. I tried it right away, using the arrow keys—with very little success. Every time I almost got it into a stable orbit, it wouldn’t last. That made me wonder if the physics interactions that control orbits in the What If world are anything like those in the real universe.

The first physics concept that applies to orbital motion is, of course, gravity. There is a gravitational interaction between any two objects that have mass. For example, there is an attractive force between the Earth and the pencil you are holding in your hand, since they both have mass. If you release the pencil, it falls.

If you’re standing on the surface of the Earth, the gravitational force acting on the pencil seems to be constant. However, if you get that pencil far enough away from the Earth (like 400 kilometres away, which is the distance at which the ISS orbits), then you would notice a decrease in the gravitational interaction: The pencil would weigh less and take longer to fall.

We can model the gravitational force between two objects with the following equation:

F = G * m1 * m2 / r2

Where F is the force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between them. This equation shows that the gravitational force decreases with distance.

So, if you want to get your spacecraft into an orbit, you need to make sure that the gravitational force is balanced by the centripetal force. This is the force that keeps objects moving in a curved path, and it is equal to the mass of the object times the square of its velocity, divided by the radius of the orbit.

To put it another way, if you want to get your spacecraft into an orbit, you need to make sure that the gravitational force is balanced by the centripetal force. This means that you need to make sure that the velocity of your spacecraft is high enough to counteract the decrease in the gravitational force with distance.

Conclusion

So, if you want to get your spacecraft into an orbit, you need to make sure that you balance the gravitational force with the centripetal force. This requires you to make sure that the velocity of your spacecraft is high enough to counteract the decrease in the gravitational force with distance. With the right combination of speed and trajectory, you can achieve a stable orbit around any planet or moon.

Learn the Basics of Git in Under 10 Minutes

While the other blob stores the content of textfile . The important thing to note is blob for textfile and README.md has the same hash because the contents of both the files are exactly the same. Therefore, instead of creating two separate copies of the same blob, git will store a single blob. We’ll now dive a little deeper into the object database.

git fundamentals

Nearly every open-source project uses GitHub to manage their projects. Using GitHub is free if your project is open source, and it includes a wiki and issue tracker that makes it easy to include more in-depth documentation and get feedback about your project. You will learn about installing Git on various operating systems, configuring Git for your needs, and then how to work locally and remotely with Git. Please note that these range notation can be used with both gitkand git log. Which will automatically notice any modified (but not new) files, addthem to the index, and commit, all in one step. You’ve now initialized the working directory—​you may notice a newdirectory created, named .git.

GitLab with Git Fundamentals Training

If Alice has made her own changes in the meantime,then she may need to manually fix any conflicts. Using a VCS also means that if you screw things up or lose files, you can generally recover easily. And sometimes you just want to know “who wrote this crap”, and having access to that information is worthwhile ?. At its very core, git is a simple key-value store, a simple structure that maps keys to values and this structure is persistent i.e. it’s stored in our disk. It can be any kind of content, be it a text file or binary file, etc. We can provide a value to git and git will calculate a unique key for it, which can be used later to retrieve the content.

The primary use of this system is to manage and keep track of your source code during software development. Whenever you develop a software application, there is often a requirement to track down the source code to review new changes and revert to any previous versions if required. Git is an open-source tool backed by a strong community that periodically improves this tool. In this course, you will learn about the workflow of Git, its commands and how to integrate it with an IDE like Eclipse. We will start with the installation of Git on both Windows and Mac operating systems. After that, we will teach you how to track your project using the Git init command.

What are the benefits of taking an online Git course?‎

It’s easy to come back to the previous version and contribute your work. GitHub takes care of this problem by keeping track of all the changes that have been pushed to the repository. This basically means that Git is a content tracker. So Git can be used to store content — and it is mostly used to store code because of the other features it provides. Through platforms like GitHub, Git also provides more opportunities for project transparency and collaboration. Public repositories help teams work together to build the best possible final product.

  • It is basically the history tab for your code editor(With no incognito mode ?).
  • Insert the missing part of the command to check which version of Git (if any) is installed.
  • It’s easy to come back to the previous version and contribute your work.
  • Since it’s not about learning the commands, instead it’s about learning the conceptual model.
  • Work is organized into repositories where developers can outline requirements or direction and set expectations for team members.

To clone a repository means that you’re taking a repository that’s on the server and cloning it to your computer – just like downloading it. On the repository page, you need to get the “HTTPS” address. Pick a name for your first repository, add a small description, check the ‘Initialize this repository with a README’ box, and click git fundamentals on the “Create repository” button. Type 1 involves creating a totally fresh repository on GitHub, cloning it to our computer, working on our project, and pushing it back. Much like using Microsoft Word or Google Drive, you can have a version history of your code so that previous versions are not lost with every iteration.
