Abstract

The invention belongs to the technical field of a teaching device and especially relates to an acceleration test device for physical mechanics learning. For the problems that an existing teaching device is single in function and is not convenient for multiple adjustment and conversion, and meanwhile, extra devices are needed for slope acceleration experiment, and the cost is increased and the like, the invention provides the following scheme: the acceleration test device comprises a free-fall acceleration tube and an initial acceleration tube. The free-fall acceleration tube is internally provided with a first external thread, a first sealing ring, a first inner groove and a first groove. The inner wall of the first inner groove is slidably connected with a silica gel sleeve. The inner wall of the silica gel sleeve is fixedly connected with a first magnet. The initial acceleration tube is internally provided with a second seal ring, a second inner groove, a second groove and a second external thread. The outer surface of the initial acceleration tube is fixedly connected with an elastic bearing sleeve. The device achieves an effect of free fall experiment. One experiment device cando multiple experiments, thereby improving work efficiency; the device is convenient to replace and can effectively save cost.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to an acceleration experiment device for learning physics and mechanics. Background technique [0002] Acceleration is a physical quantity in physics. It is a vector. It is mainly used in classical physics. It is generally represented by the letter a. The unit in the International System of Units is meters per square second. Acceleration is the rate of change of the velocity vector with respect to time. It describes the direction of velocity and the speed of size change. In physics teaching activities, it is necessary to use various teaching aids to assist teaching. It is beneficial for teachers to explain as easily as possible. It is also helpful for students to understand and understand what they have learned more quickly. Based on the single function of the existing teaching device, it is inconvenient for multiple adjustments and conversions. At the same time, the incli...
