A summary of the new knowledge points of ninth grade physics
The following is a summary of the new version of ninth grade physics: I. Mechanics Newton's first law: When an object is not affected by an external force, it will remain at rest or move in a straight line at a constant speed. 2 Newton's second law: The external force on a body is equal to the product of the mass of the body and the acceleration, F=ma. 3. Newton's three laws of motion, including the law of inertia, the law of action-reaction, and the law of universal gravitation. 4. Uniform linear motion and variable speed linear motion: Uniform linear motion refers to constant speed or uniform rate linear motion. 5. Description of motion: motion is the change of the state of an object. It can be described by the laws that describe the state of motion of an object. 6. Stationary state: When an object is at rest, its mass remains constant and its acceleration is zero. 7. Uniform acceleration of linear motion: The linear motion of an object under acceleration does not change the direction at any time. 8. The application of Newton's law of motion, including flat projectile motion, simple resonant vibration, spring ergometer, etc. Second, Heat The first law of energetics: heat always flows from a hot object to a cold object until the temperature of the two objects is equal. The second law of energetics: heat cannot spontaneously transfer from a low-temperature object to a high-temperature object. 3. Heat transfer: Heat is transferred through contact between objects or contact between gases, liquids, and solid. 4. The properties of an ideal gas: An ideal gas has the properties of an isothormic expansion and isothormic contraction. That is, the volume can change at will when the temperature is constant. The density is equal to the function of the temperature. 5. thermal expansion: When the temperature of an object changes, its volume will also change, causing the volume of the object to change with the temperature. 6. Thermodynomics applications: Including the equations of energetics, heat transfer, thermal radiation, etc. Electricity 1. Electric field: The electric field is the electric field line produced by the distribution of electric charges. The strength of the electric field is related to the density of electric charges. Potential: Potential is the moral height of a point on the electric field line, indicating the potential at that point. 3. Current: The current generated by the movement of electric charges in the electric field is related to the amount of electric charge, the strength of the electric field, and the potential difference. 4. Ohm's Law: Current is proportional to the product of voltage and resistance, and inverse to resistance. 5. Basic circuit: including circuit components, basic circuit laws, current and voltage in the circuit. 6. The interference in the circuit, including electromagnetic interference, signal interference, etc.
