Classification and review of junior high school physics experiments.

Part I: Theoretical Basis.

1. Theory of measurement.

a) Measure the essence.

Measurement is a comparison. In order to make a scientific comparison, there needs to be a recognized standard quantity as the basis for comparison, and this standard quantity is called

In order to facilitate communication, a set of internationally accepted unit systems - the "International System of Units", abbreviated as "SI". Please fill in the principal units of each of the following quantities in the International System of Units:

Mechanics, electricity, thermothermal fluctuations, and acoustic function and energy

Length, Current, Temperature, Frequency, Function, Energy, Time, Voltage, Period, Power, Quality, Resistance, Amplitude, Density, Wavelength, Speed, Loudness, Force, Pressure

2) Error theory.

1. Errors and errors.

The difference between the measured value and the true value is called the error. Any measurement will have errors, which can not be absolutely avoided; And mistakes can and should be avoided.

2. Factors influencing error.

1) Measuring tools. The more precise the tools used for the measurement, the deeper the error becomes

2) The method of measurement.

3) Estimation. Measurements always have to be estimated, so measurements always have to produce errors.

3. Methods to reduce errors.

1) The error can be reduced by using more precise measurement tools and designing more scientific measurement methods.

2) Multiple measurements, taking is an important way to reduce the error.

Note: 1) "Multiple measurements", usually three times;

2) When taking an average, the digits of the average value must be the same as the digits of the measured value.

2. Science**.

Science** generally goes through the following seven steps: Due to the divergent nature of "conjectures and hypotheses", it is less likely to occur in exams. We emphasize that "conjectures and hypotheses" must be made reasonably on the basis of the situation of the test questions, and arbitrary conjectures are opposed. 4 Second.
