What was it again about the inclined plane? What belongs to a circuit? And how does nuclear fission work? The physics trainer conveys the most important learning content of physics for grades 7 to 10 in eleven independently manageable chapters. These include acoustics, atomic physics, electricity, electronics, energy, entropy, magnetism, mechanics, optics, pressure, and thermodynamics. A practical aid for review is the formula collection with fundamental formulas, quantities, and units - a good overview at the end of the volume.
