Test bench capable of performing various physical experiments

Abstract

The invention discloses a test bench capable of performing various physical experiments. The test bench comprises an operation panel. Support legs are arranged at four corners of the bottom of the operation panel. A first support bar is arranged at one side above the operation panel. A second support bar is arranged at the top of the first support bar. The top of the operation panel is provided with a storage tank. A movable plate is arranged in the storage tank. Through a mounting plate, a spring dynamometer and a second fixed pulley, a friction experiment is carried on the operation panel. Through the first support bar, the second support bar, a fixing rack and a ticker-tape timer, a freely falling motion test is carried out. Through an inclined plate, a horizontal plate and a stop block, a horizontal projectile motion experiment is carried out. Under the action of a rotation shaft, an electric lifting rod pushed a movable plate up so that the inclined angle between the movable plateand the horizontal direction is changed. Through a first fixed pulley, the Newton's second law experiment can be verified.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to an experiment platform capable of performing various physical experiments. Background technique [0002] Physics itself is an experimental science, it is based on observation and experiment, and physical experiment is the only standard to test the correctness of the theory, which can not only deepen students' impression of the knowledge they have learned, but also improve students' hands-on ability, Fully cultivate students' innovative spirit and adaptability. [0003] Physical experiments can be divided into many types, such as friction experiments, free fall experiments, flat throw experiments and Newton's second law experiments, etc. The physical experiment table is a table for students to do physical experiments, and is often used to verify the physical experiment. Theorems and laws, but the existing physical experiment benches cannot satisfy a variety of experiments on one...

[0003] Physical experiments can be divided into many types, such as friction experiments, free fall experiments, flat throw experiments and Newton's second law experiments, etc. The physical experiment table is a table for students to do physical experiments, and is often used to verify the physical experiment. Theorems and laws, but the existing physical experiment benches cannot meet the needs of one experiment bench for multiple experiments, which is very inconvenient to use and reduces the learning efficiency of students
