Molecular Models vs Physics by Voice

Molecular Models - 3D Explore the world of molecules in stunning 3D!. Molecular Models - 3D helps you visualize and understand molecular structures interactively. Whether you're a student, teacher, or science enthusiast, this app makes chemistry come alive with beautiful 3D renderings. Rotate, zoom, and explore atoms, bonds, and molecular geometry with intuitive gestures. Instantly search for molecules like Water (H₂O), Hydrogen Sulfide (H₂S), Hydrogen Peroxide (H₂O₂), Carbon Dioxide (CO₂) and more - all displayed in spatial their arrangements.

Physics by Voice is an interactive mechanics course built around an original step-by-step teaching method. The course begins with the most fundamental questions: what “where” means, how a coordinate and a reference frame describe position, and how motion is represented as a change in position. It then introduces velocity, acceleration, forces, Newton’s laws, work, and energy one concept at a time. The app includes: • 18 sequential mechanics lessons • Spoken explanations and questions • Speech recognition for answers • Clear coordinate, vector, and force diagrams • Practice problems with detailed solutions • Russian and English languages • Progress stored locally on the device • No advertising and no in-app purchases Course topics include: • Foundations of physical quantities and formulas • Kinematics and reference frames • Vectors, free fall, and circular motion • Dynamics and Newton’s laws • Gravitation, weight, and weightlessness • Pressure and Archimedes’ principle • Momentum, friction, and torque • Center of gravity and equilibrium • Work, power, kinetic energy, and potential energy Microphone and speech-recognition access are used only for voice interaction. The app has no user accounts, advertising, or developer-operated data collection.
