Main learning contents of junior high school physics:
1, grade one: sound phenomenon, light phenomenon, lens and its application (concave lens and convex lens), state change (melting, solidification, vaporization, liquefaction, sublimation, sublimation), current and circuit (series and parallel). ?
2. The second day: ohm's law (voltage), electricity (electric energy, electricity and heat), electricity and magnetism (magnetic field, electromagnetism, motor, electromagnetic relay), information transmission (telephone, electromagnetic wave). ?
3. Three levels: matter (mass and density), motion and force (force, Newton's first law, balance of two forces), force and machinery (elasticity, gravity, friction, lever), pressure and buoyancy, work and mechanical energy (mechanical efficiency, power, kinetic energy and potential energy, conversion of mechanical energy), heat and energy (internal energy and thermal energy), and energy (energy).
