Questions and methods: please describe briefly the content of newton iii and its application. Methodology: recall the definition of the third law of newton, i. E. That the force is equal to the reactionary force, is opposite to the reactionary force and works in the same line. Examples are then given of their use in life, such as swimming, basketball, etc. Answer: newton's third law states that there is a force and a reaction between any two objects, equal size, opposite direction, on the same line. Examples of applications are: when swimming, people row back and water gives people a push forward; when playing basketball, hands give basketball a force up and basketball a force down. Question: please explain the reflection of light and give an example. Method: refraction of light means a change in the direction of the light as it enters another medium from one medium. The reason for the reflection is that light is transmitted at different speeds in different media. For example, when a chopstick is inserted into the water, from the surface, the chopstick appears to have turned. Answer: the reflection of light refers to a change in the direction of transmission when light enters another medium from one medium. The reason is that light is spreading at different speeds in different media. Example: a chopstick is inserted into the water, from the surface of the water, and it seems to have turned. Question: please elaborate on the contents of the om law and draw a map of the relationship between current, voltage and resistance. Methodology: the content of om's law is that in electrical circuits the current of the conductor is proportional to the voltage at both ends, and inversely to the resistance of the conductor. In mathematical formula i = u/r, i = current, u = voltage and r = resistance. Relationship chart: current i is proportional to voltage u, inversely to resist r. Answer: the om law says that in electrical circuits, the current of the conductor is proportional to the voltage at both ends, and to the resistance of the conductor. The mathematical formula is i = u/r. Relationship chart: current i is proportional to voltage u, inversely to resist r. Question: please explain what is merit and give an example. Method: the power is the effect of the force on the object, expressed as w and in jj. The calculation formula is w = fxsxcosium, where f is force, s is the shift of the force's function points, and the arc of the force's direction and direction. For example, a man who raised a box and lifted it a metre from the ground did 100 joules to it. Answer: it is the effect of power on the activity of the object, in w and in jj. The formula is w=fxsxcosium. Example: a man lifts a box one metre from the ground and does 100 joules to it. Question: please explain what energy is constant and give an example. Method: the constant law of energy means that energy cannot be created or eliminated in a closed system, can only be converted from one form to another or transferred from one object to another. The total energy remains unchanged. Example: an object falls from a high point of view and gravity force is converted to kinetic energy, but total energy (gravitational force + kinetic energy) remains unchanged. Answer: the constant law of energy means that energy cannot be created or eliminated in a closed system, but can only be transformed from one form to another or transferred from one object to another. Example: an object falls from a high point of view and gravity forces are converted to kinetic energy, but total energy (gravity forces + kinetic) remains unchanged. Question: please explain what the law of thermodynamics is and give an example. Method: the first law of thermodynamics, also known as the law of energy persistence, means that energy cannot be created or eliminated in a closed system, can only be converted from one form to another, or transferred from one object to another. The total energy remains unchanged. For example, an object absorbs heat and can increase inside, while the object works externally and reduces, but the total energy remains constant. Answer: the first law of thermodynamics, also known as the law of energy persistence, means that energy cannot be created or eliminated in a closed system, can only be converted from one form to another or transferred from one object to another. Example: an object absorbs heat and is able to increase inside, while the object is able to perform external functions and decrease internally, but the total energy remains constant. Question: please explain what is relativity and outline its rationale. Methodology: the theory of relativity is that of physics proposed by einstein and includes mainly narrow relativity and general relativism. At the heart of narrow relativism are two basic assumptions: the laws of physics are the same in all inertial reference systems and the speed of light is constant in a vacuum. The general relativism is the study of gravitational phenomena and other related knowledge and subjects: the subject: please explain what energy is constant and explain its importance in physics. Method: the constant law of energy means that energy cannot be created or eliminated in a closed system, can only be converted from one form to another or transferred from one object to another. This must be one of the most basic laws of physics, revealing the pattern of balance and transformation of energy in the universe. In solving the problem, emphasis is placed on the importance of the constant law of energy in interpreting and predicting physical phenomena. Answer: the constant law of energy means that energy cannot be created or eliminated in a closed system, but can only be transformed from one form to another or transferred from one object to another. This must be important in physics, which is one of the bases for interpreting and predicting physical phenomena. For example, it can be used to explain phenomena such as the movement of objects, heat transfer, electromagnetic wave transmission, etc. Question: please describe the differences and linkages between newton's law and newton's second law. Method: newton muster, also known as inertia, states that all objects remain static or even-paced in line motion without external force. Newton's second law, also known as the law of power, states that the acceleration of an object is proportional to the external force above it, inversely to its mass, in the same direction as the external force. In solving the problem, emphasis is placed on the complementarity of these two laws in describing the movement of objects. Answer: newton's law is both newton's law and newton's second law, which describe the movement of objects. They are closely related and distinguishable. Newton’s law emphasizes the inertia of objects, i. E. They remain static or even-paced in line motion without external force. Newton's second law gives a quantitative relation to a change in the object's state of motion, i. E. The acceleration of the object is proportional to the external force above it, inversely to its mass, in the same direction as the external force. Question: please explain what quantum mechanics are and outline its rationale. Methodology: quantum mechanics is a physical branch of the study of microparticle motion patterns. It is based on the principles of wave idity, uncertainty, energy quantumization, etc. In solving the problem, emphasis is placed on the importance of quantum mechanics in interpreting micro-world phenomena. Answer: quantum mechanics is a physical branch of the study of microparticle motion patterns. It is based on principles such as the duality of wave grains, i. E. The fact that microparticles are both particle- and volatile; the principle of uncertainty, i. E. That the position and momentum of the particles cannot be measured precisely at the microscale at the same time; and energy quantumization, i. E. That the energy of microparticles exists in discrete quantum form。quantum mechanics is important in the interpretation of micro-world phenomena such as atomic structures, molecular chemistry, semiconductor devices, etc. Question: please elaborate on the rationale for relativity and describe its application in modern physics. Methodology: the theory of relativity is that of physics proposed by einstein and includes mainly narrow relativity and general relativism. At the heart of narrow relativism are two basic assumptions: the laws of physics are the same in all inertial reference systems and the speed of light is constant in a vacuum. The general relativism is the temporal and temporal curve theory of the gravitational phenomenon. In solving the problem, the importance of relativity in modern physics is emphasized. Answer: the theory of relativity is that of physics, as proposed by einstein, and includes mainly narrow relativity and general relativity. The rationale for narrow relativism is that the laws of physics are the same in all inertial reference systems and that the speed of light is constant in a vacuum. The general relativism is the temporal and temporal curve theory of the gravitational phenomenon. Relativity is important in modern physics, for example, where it can be used to explain phenomena such as black holes and cosmic explosions. Question: please explain the principle of entropy and explain its role in thermodynamics. Method: the principle of entropy means that in a closed system, entropy (the physical amount indicating the degree of disorder in the system) tends to increase. This principle is at the heart of the second law of thermodynamics, and it reveals the direction in which processes take place in nature. In solving the problem, emphasis is placed on the importance of the principle of entropy in describing the direction of processes in nature. Answer: the entropy principle is that in a closed system, entropy tends to increase. This principle is at the heart of the second law of thermodynamics, and it reveals the direction in which processes take place in nature. For example, it can be used to explain why heat always comes from
