: Speed, mass, density, gravity, elastic force, and friction. : Molecules, diffusion, and states of matter
These are organized by the main chapters of the 7th-grade curriculum. They usually offer three levels of complexity to help students practice basic concepts: and error. : Speed
The (typically by authors like Maron or Peryshkin) are supplementary collections of exercises designed to reinforce the main textbook. A "reshebnik" (solution guide) for these materials generally includes the following content structure: 1. Training Tasks (Trenirovochnye Zadaniya)
: Simple machines (levers, pulleys), efficiency, and potential/kinetic energy. 2. Self-Study Tests (Samostoyatelnye Raboty)
