Is the digital experiment a virtual experiment?

Digital experiment is a kind of virtual experiment.

Digital experimental operation consists of five parts: experimental equipment, experimental sensor, digital collector, computer and display screen, in which experimental equipment is the necessary equipment for physical experimental operation; Sensors are used in physics to collect non-electrical signals such as light, heat and force. The data collector is a signal conversion device connecting sensors and computer equipment. A computer is a device for processing information.

Digital experiments can further improve the accuracy of physical experiments with the application of modern information technology such as computers and sensors. Because there is no need for real equipment experiments, digital experiments belong to virtual experiments.

Comparison between digital experiment and traditional experiment in senior high school;

1, information acquisition and conversion function. The information obtained by digital experiment has the advantages of high density, high speed, high sensitivity, little interference from external environment, and the measurement unit can be changed at will. The traditional physical experimental instruments have low sensitivity and density to obtain information, and are greatly disturbed by the external environment.

2. Information operation and saving function. Digital experiment has powerful information operation and management functions, and can save continuous information in real time when it is used. The traditional physical experimental instruments take manual calculation as the main form and can only record and store simple "point" signals.

3. Information display and operation function. The information display of digital experiment system has many forms, such as tables, images, numerical values and so on. , powerful display function, convenient and complete record. The traditional experimental instrument is a kind of analog display mode, which has the defects of slow running speed, lag and incompleteness in use.
