Click on one of the physics simulations below... you'll see them animating in real time, and be able to interact with them by dragging objects or changing parameters like gravity.
A resident of Delhi was trapped by a fake Facebook profile and a threatening video call, which led to repeated extortion demands totaling Rs. 2.52 lakh. The Delhi Police's cyber unit initiated a detailed investigation, analyzing the fake Facebook profile, WhatsApp account data, Internet Protocol Detail Records (IPDRs) , and bank transaction details. They traced the digital trail back to an accused, Abas Khan, in Rajasthan's Alwar district, arrested him, and recovered an iPhone used in the crime.
To help narrow down the source of your specific issue, please let me know:
Fake accounts are tools, not social identities. They are often created very recently and lack any real history or timeline of activity. Check the "About" section of the profile to see when the account was created. A brand new account isn't a definitive sign on its own, but combined with other warning flags, it's a strong indicator of a dummy account.
Every account has a unique numerical ID that remains permanent, even if the user changes their display name or custom URL username. View the dummy account's profile page. how to trace dummy account in facebook
| Data obtainable by Facebook | Potential tracing outcome | |-----------------------------|----------------------------| | Registration IP address | ISP subscriber identity | | Last 10 login IPs | Geolocation + device fingerprint | | Phone number (verified) | Carrier subscriber info | | Email address (verified) | Other linked accounts | | Device ID / Browser fingerprint | Cross-account correlation | | Session cookies | Real account takeover detection |
People are creatures of habit and often reuse the same alias across gaming forums, TikTok, or Reddit. 2. Grabify IP Logger (Requires Interaction)
Go beyond the surface-level red flags. Use Facebook's own search function to dig deeper. You can search by name, phone number, or email address if you have it. Using the "site" operator in Google (e.g., "Full Name" site:facebook.com ) can sometimes surface profiles that don't appear in Facebook's own search due to privacy settings. A resident of Delhi was trapped by a
However, it is crucial to understand your limits as a private citizen. While there are clear warning signs to spot a dummy account and immediate steps you can take to protect yourself, private individuals have to forcibly unmask the operator of a fake account. This article provides a comprehensive guide on how to identify, protect yourself from, and escalate the issue of dummy accounts on Facebook, while clearly explaining the legal and technical boundaries that separate civilian investigation from law enforcement work.
Legally, only law enforcement agencies can obtain this hidden data. They do this by serving a subpoena or legal warrant to Meta during criminal investigations involving harassment, fraud, or threats. Step 1: Extract Hidden Contact Info
If a fake account is being used for harassment, impersonation, or fraudulent activities, it is important to follow official channels to address the issue: They traced the digital trail back to an
Even if the dummy account has privacy settings, you can see .
Facebook protects user data fiercely. You cannot simply click a profile and see the real name or IP address of the creator. To trace a dummy account, you must act like a digital detective, looking for slip-ups, linked accounts, and patterns in their behavior. Phase 1: Analyze the Profile for Clues

myPhysicsLab is provided as open source software under the Apache 2.0 License. Source code is available at https://github.com/myphysicslab/myphysicslab. Online documentation is available.
There are around 50 different simulations in the source code, each of which has an example file which is for development and testing. There are also downloadable versions which be used to show simulations offline (when not connected to the internet).
Most of the simulation web pages show how the math is derived. See for example the Single Spring simulation.
The rigid body physics engine is the most sophisticated simulation shown here. It is capable of replicating all of the other more specialized simulations. The physics engine handles collisions and also calculates contact forces which allow objects to push against each other.

The myPhysicsLab simulations do not have units of measurements specified such as meters, kilograms, seconds. The units are dimensionless, they can be interpreted however you want, but they must be consistent within the simulation.
For example if we regard a unit of distance as one meter and a unit of time as one second, then a unit of velocity must be one meter/second.
See the discussion About Units Of Measurement in the myPhysicsLab Documentation.
Hi, my name is , I live in Seattle, WA, USA, and I am a self-employed software engineer. I started developing this website in 2001, both as a personal project to learn scientific computing, and with a vision of developing an online science museum. I grew up in Chicago near the Museum of Science and Industry which I loved to visit and learn about science and math.
I got a BA in Mathematics at Oberlin College, Ohio, 1978, and an MBA from Univerity of Chicago, 1984. My first software jobs were using the language APL which I enjoyed for its math-like conciseness and power.
I was fortunate to get involved in the Macintosh software industry early on in 1985, joining MacroMind, which became Macromedia. I led the software development at MacroMind as VP of Engineering for 5 years. Our most significant product was VideoWorks, which was renamed Director, and lives on today as Adobe Director. In the 1980's, the interactive multimedia concepts that are so common today were new and being developed. VideoWorks was mainly an animation tool, but also incorporated programmable interactivity. Our main competitors at that time were HyperCard, SuperCard, and Authorware. Director was used in many different ways; I am most proud that it became the preferred way to prototype software user interfaces for a time during the 90's. Director was also used to develop the introductory "guided tour" tutorial that came with the Macintosh in the early years. And of course, Director was used for all sorts of art, design, and marketing projects.
I went on to work at Apple Computer on new multimedia and user interface concepts involving digital agents, animated user interfaces, speech recognition and distributed information access. In 1991, there was a sudden flurry of activity when Apple and IBM were trying to set up a strategic partnership. I became involved in the super-secret negotiations, and made the suggestion that what the world needed was a standard for multimedia that multimedia content creators could rely on to publish to (ultimately this is what HTML became). Based on these suggestions, Kaleida Labs was founded. Our work there developed a product called ScriptX, which turned out to be very similar to Sun's Java which was being developed at the same time. ScriptX had goals of supporting all forms of multimedia: text, images, audio, video, animation; being cross-platform (Mac and Windows), interpreted, object oriented, with a garbage collector to manage memory.
I then moved to Seattle and turned my attention back to mathematics and science. I relearned calculus by doing all the problems in my old college text book and took further math classes at the University of Washington. I started developing this website as a way to practice what I was learning. I am now happy to use excellent tools such as HTML and JavaScript, and leave their development to others. I continue to work on physics simulations, with several new ones in development.
