Physics by Voice

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.
