The basic problems of junior high school physics, the physicists who are required to know junior high school physics, and their corresponding inventions
Alright, here are some basic physics problems in junior high school and the corresponding physicists and their corresponding inventions: What is Newton's first law? A: Newton's first law states that any object will remain stationary or move in a straight line at a constant speed without the effect of an external force. Physicist: Isaac Newton The discoverer of Newton's first law was the British scientist Isaac Newton. 2 What is electricity? A: Electricity is a physical phenomenon that can be expressed as the interaction between electric charges. Physicist: Isaac Hendrikse [Description: Coulomb's law states that the interaction force between two electric charges is inverse proportional to the square of the distance between them.] 3 What is a magnetic field? A: Magnetic fields are generated by electric currents and can be expressed as the surrounding magnetic field around magnetic objects. Physicist: John James Clerk Maxwell [Description: Maxwell's equations describe the laws of motion of the electromagnetic field, including Ampere's law and the Farady's law of electromagnetic induction.] What is the reflection of light? A: When light shines on the surface of an object, part of the light will be reflected back, and the other part will penetrate the object and enter the air. Physicist: Aristotle [Creation: The law of light reflection proposed by aristotle.] What is electromagnetic wave? A: Electromagnetic waves are a kind of physical medium that will not be weakened during transmission. They can be expressed as radio waves, microwave, infrared rays, visible light, and so on. Physics: Maxwell [Description: Maxwell's equations describe the law of electromagnetic wave transmission.] 6 What is heat? A: Heat is a physical phenomenon that can be expressed as a change in the temperature of an object. Physicist: John Wallis The law of heat transfer states that the speed at which heat is transferred from a high-temperature object to a low-temperature object is inverse to the temperature of the object. 7 What is pressure?
Was university physics suitable for junior high school students?
Physics knowledge in university was more complicated and involved many advanced concepts and theories. It might be difficult for junior high school students to understand. Therefore, it was not suitable for junior high school students to study physics in university. They had to wait until they had mastered more basic knowledge before they looked back. Of course, if junior high school students were interested in physics, they could read some basic physics textbooks to understand some basic concepts and principles before gradually studying them in depth.
Junior high school physics liquefied knowledge points
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state, which would release heat to the outside world. There were two ways to achieve liquification. One was to lower the temperature (all gases could be liquefied when the temperature dropped enough), and the other was to compress the volume (at a certain temperature, compressing the volume of some gases could make them liquefied. Some gases might need to be cooled down before compressing the volume; if the temperature of the gas was higher than its critical temperature, it could not be liquefied by compression). The critical temperature was the highest temperature at which a gas could be liquefied. Liquefaction had many practical applications. Compared to gases, it could greatly reduce the volume (about 1/1000 of the volume of the gas), making it easy to store and transport. For example, gases such as hydrogen and natural gas had a higher critical point and could be turned into liquid by pressurizing at room temperature. However, gases such as hydrogen and nitrogen had very low critical points and needed to be deeply cooled to be liquefied at the same time. The formation of dew and fog in nature was caused by the decrease in temperature, which caused the water vapor to be liquefied. This was an example of lowering the temperature and causing it to be liquefied. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
Junior high school physics and chemistry knowledge points summary
** I. Introduction of Junior High School Physics Knowledge Points ** 1. ** Matter and molecules ** - Matter was made up of molecules. There were gaps between the molecules, and there were attractive and repulsive forces between the molecules. 2. ** Measuring related ** - The reading of the scale should be read to the next place of the division value. When using the scale to measure, it can be measured many times to reduce the error. - The measuring cylinder could be used to measure the volume of liquid and the volume of solid using the "drainage method." - Using a scale to measure mass followed the principle of "left object right code". 3. ** Density-related ** - The density of the same substance was related to its state. For example, water and ice had different density due to their different states. The density of water is 1 (<rho_{water>= 1.0> times10 ^{3}kg/m^{3}=1g/cm^{3}). 4. ** Sports related ** - The movement and stillness of matter were relative to a reference object. The reference object could be chosen at will, but the object being studied could not be used as a reference object. With respect to the reference object, the position of the object changes and the object moves. - The average speed represents the speed of an object's movement over a period of time or distance, and the instantaneous speed represents the speed of an object's movement at a certain position or time. 5. ** Sound-related ** - All objects that made sound were vibrating. Sound needed a medium to travel. Usually, sound traveled the fastest in solid objects, followed by liquids, and the slowest in gases. - The boundaries between music and noise were not strict. It was related to the location, time, environment, and people's mood. The three elements of music included pitch (high or low), loudness (loud or low), and timbre (distinguishing different vocal bodies). The prevention and control of noise should start from the sound source, the transmission path, and the human ear. 6. ** Mechanics related ** - The effect of force was mutual. The object that exerted force was also the object that received force. The effect of force is to cause the object to change shape and change the state of motion of the object. Whether the state of motion of an object has changed can be determined by changing one or both of the speed and direction, or whether the object is not in a state of static or uniform linear motion. The three elements of force were the magnitude, direction, and point of effect of the force. There was a simple way to draw a force diagram. The spring force tester was made according to the principle that the greater the pulling force, the greater the spring's displacement. ** 2. Junior high school chemistry knowledge summary ** 1. ** The chemical properties of common substances ** - Common substances have different colors, such as red solid copper and iron dioxide; green solid basic copper carbonates; blue solid copper dioxide and copper sulfuric acid crystals; purplish-black solid is potassium Permanganate, etc. Among the liquids, colorless liquids such as water and hydrogen peroxide-dioxide; blue solutions such as copper sulfate-dioxide solution; light green solutions such as iron sulfate-dioxide solution; yellow solutions such as iron sulfate-dioxide solution; purplish-red solutions such as potassium peroxide-dioxide solution; and purple solutions such as litmus solution. Among the gases, the reddish-brown gas was nitrogen dioxide, the yellow-green gas was Cl2, and most gases such as oxygen and nitrogen were colorless gases. 2. ** Chemistry related (Elemental characteristics)** - For example,"I'm hydrogen, I'm the lightest, and the rocket depends on me to transport the satellite. I'm helium, I'm a scoundrel, I'm the worst at losing and gaining electrons. "I'm lithium, so the density is low. I'll soak in water and acid…" 3. ** Other Important Knowledge Points ** - In ancient China, the three major chemical processes were paper making, gunpowder making, and porcelain burning. There were three types of oxygen reactions: explosion, combustion, and slow oxygen. The three kinds of particles that make up matter are molecules, atoms, and ions, while the three kinds of particles that are not charged are molecules, atoms, and neutrons.
