Physics by Voice

Learn mechanics step by step: listen to explanations, explore clear diagrams, answer aloud, and reinforce every topic with worked problems.

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.
