Unlike basic calculators, this app is designed for real understanding. It not only gives answers but also helps you learn how gravitational force works in real physics scenarios. FAST. ACCURATE. EDUCATIONAL. Built for performance, clarity, and learning. Newton’s Law of Gravity states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. This Newton’s Law of Gravity Calculator is used to calculate and find the gravitational force between two objects, considering their mass and the distance between them. Formulas: 1. Gravitational Force: F = Gm₁m₂/ r² 2. Mass of Object 1: m₁ = Fr²/ Gm₂ 3. Mass of Object 2: m₂ = Fr²/ Gm₁ 4. Distance between the Objects: r = √(Gm₁ m₂/F) Where, G = Universal Gravitational Constant = 6.6726 x 10⁻¹¹N-m²/kg² m₁ = Mass of Object 1 m₂ = Mass of Object 2 r = Distance Between the Objects. Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including objects ranging from electrons and atoms to planets, stars, and galaxies. Since energy and mass are equivalent, all forms of energy (including photons and light) cause gravitation and are under its influence. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects. Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force but as a consequence of the curvature of spacetime caused by the uneven distribution of mass. The most extreme example of this curvature of spacetime is a black hole, from which nothing—not even light—can escape once past the black hole's event horizon. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force that causes any two bodies to be attracted to each other, with the force proportional to the product of their masses and inversely proportional to the square of the distance between them.

• Paranoia File Encryption is a universal file encryption application for iOS (iPhone/iPad/iPod), brought to you by Paranoia Works. It securely encrypts your private and confidential files or entire folders. P.F.E. works like an archiver, creating a new .enc file after encryption. The original file(s) can be deleted or wiped after the encryption process is completed. This can be done manually or set to be done automatically. • The app ensures real security as data is encrypted using the strongest encryption algorithms: Blowfish 448bit, AES 256bit, RC6 256bit, Serpent 256bit, Twofish 256bit, Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit ciphers are available. • Steganography: The application offers steganographic features, allowing you to conceal files within a JPEG image. Two algorithms are available: J-UNIWARD and F5. The selected algorithm works with your chosen symmetric cipher to create the final steganogram. • Versions for other systems and platforms are available on the application's homepage (download section - https://paranoiaworks.mobi/download/). • The AES web version is available at: https://pteo.paranoiaworks.mobi/paranoia-file-encryption/ • Free / PRO version differences: The PRO version contains more algorithms - specifically, Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit (which is a cascade of Threefish–Serpent–AES–SHACAL2). The free version can decrypt data encrypted by these advanced algorithms, but encryption is exclusive to the PRO version. In addition, the PRO version allows the selection of multiple files and their batch processing. It also provides a key to activate the PRO version of the desktop application: Paranoia File & Text Encryption for PC, Paranoia Text Encryption for PC and S.S.E. File Encryptor for PC • We greatly appreciate your feedback, including suggestions for improvement and reports of technical problems.
