What are some interesting physics research topics?

Water rockets and fire rockets work very well.

The physics research projects include: Thomas Young's double-slit demonstration applied to the electron interference experiment, Galileo's free fall experiment, Robert Milligan's oil drop experiment, Newton's prism decomposition of sunlight, Thomas Young's light interference experiment, Cavendish torque experiment, Eratosthenes's measurement of the circumference of the earth, Galileo's acceleration experiment, Rutherford scattering and the nuclear model of the atom, and Michel Foucault's pendulum experiment. Ten very famous scientific research projects.

Scientific experiments are the foundation of the development of physics, and they are the only means to test the theories of physics, especially the development of modern physics, which is closely related to experiments. The development of modern experimental technology has continuously revealed and discovered various new physical phenomena, deepened people's correct understanding of the laws of the objective world, and promoted the development of physics.

The main book of physics in middle school should be scientific research methods

1) Equivalence (substitution);

2) Establish an ideal model method;

3) control variable method;

4) Experimental reasoning;

5) the conversion method is quiet;

5) Analogy, etc.

The research methods of physical science include the control variable method, the equivalent substitution method, the analogical reasoning method, and the model method, and the main indication methods commonly used in mechanics include the integral method, the isolation method, and the image method, and the main method in electricity is the equivalent substitution method of the circuit.

Physics is the study of the most general laws of the motion of matter and the basic structure of matter. As a leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, and thus becomes the research basis of other scientific disciplines.

1. Control variable method: by fixing a few factors into a number of single factors to affect the size of a certain amount.

1. Factors affecting the speed of evaporation; 2. What factors are related to the effect of pressure;

3. Study what factors are related to the magnitude of sliding friction; 4. Factors affecting the size of resistance;

5. Study the relationship between current, voltage and resistance (Ohm's law); 6. What factors are related to the magnetic strength of the electromagnet?

7. Explore the action of magnetic field on electric current; 8. Study the phenomenon of electromagnetic induction; 9. Study Joule's law.

2. Equivalence method: the method of substituting a physical quantity, a physical device or a physical state (process) with another corresponding quantity to obtain the same conclusion.

1. When studying the force on the object, the resultant force is introduced. 2. Cao Chong weighed the elephant.

3. In the study of circuits composed of multiple electrical appliances, the total resistance is introduced.

3. Model method: a simplified model that reproduces the essential relationship and intrinsic characteristics of the prototype in an idealized way.

1. Introduce the concept of "light" when studying optics.

2. When studying the magnetic field, the magnetic inductance line is introduced to describe the magnetic field. 3. Ideal electricity meter.

4. Transformation method (indirect inference method).

Accumulation method: The unobservable effect (phenomenon) is accumulated by itself into observable macroscopic objects or macroscopic effects.

1. The method of compressing the lead column is used to show the gravitational effect of the molecular plane.

2. When studying molecular motion, the phenomenon of diffusion is used to study.

3. Understand the current according to the effect generated by the current.

4. Recognize the magnetic field according to the action generated by the magnet.

5. Analogy: A logical method to transfer the relevant knowledge and conclusions of one object to another object according to the similarity or similarity between two objects in some aspects.

1. Water pressure and voltage.

2. The pumping machine provides water pressure, similar to the power supply to provide voltage.

3. Introduce the pressure formula with the definition formula of velocity.

6. Comparative method: a logical method to find out the similarities or differences between the research objects.

1. Study the similarities and differences between evaporation and boiling.

2. Compare the similarities and differences between voltmeter and ammeter in the process of use.

3. Compare the similarities and differences between the structure and principle of the motor and the generator.

4. The similarities and differences between gasoline engine and diesel engine.

7. Inductive method: the method of generalizing the logic of general judgments from the judgments of a series of individual phenomena.

1. From the diffusion of gas, liquid, and solid, it is concluded that the molecules of all objects are in irregular motion.

2. Experimental laws in physics (such as the characteristics of current and voltage in series and parallel circuits) are almost all used in this method.
