Problems solved by technology

Therefore, the teaching demonstration instrument can effectively help students understand the physical phenomenon more intuitively and profoundly. The current centrifugal force teaching instrument cannot directly explain the influence of the rotational speed on the centrifugal force. It is inconvenient for students to observe and there is no reference

Abstract

The invention discloses an intuitive and understandable centrifugal force experiment table for teaching. The centrifugal force experiment table for teaching comprises supporting parts, a rail part, arotating shaft part and a measuring part, wherein the rail part is a circular rail; a rail base is arranged at the lower part of the circular rail; an annular groove is formed in the inner ring surface of the circular rail; annular cover plates are arranged on two sides of the circular rail; the supporting parts are symmetrically arranged on the two sides of the rail part and comprise support bases and adjustable supports fixedly connected with the support bases; shaft holes are formed in the upper middle portions of the adjustable supports; the rotating shaft part comprises a horizontal rotating shaft which passes through a circular ring of the circular track, and two ends respectively penetrate through shaft holes; shaft handles perpendicular to the rotating shaft are arranged at the twoends of the horizontal rotating shaft; a small experiment ball dragged by a silk thread is arranged in the middle of the rotating shaft part, namely in the circular rail; the measuring part comprisesa tension sensor, a speed sensor and a display screen in communication connection with the tension sensor and the speed sensor; the tension sensor is arranged between the silk threads; and the speedsensor is installed in the small experiment ball.

Description

technical field [0001] The invention relates to the field of teaching work, in particular to a centrifugal force safety experiment platform for teaching. Background technique [0002] In the middle school teaching process, centrifugal force is a relatively abstract physical phenomenon. In order to make it easier for students to understand centrifugal force and its characteristics, teachers teach through centrifugal force experiments. At present, the centrifugation experiment is relatively simple, and the display results are not intuitive enough. With the development of society, due to the needs of teaching, it is necessary to have a deeper understanding of some physical phenomena. Experimental teaching can directly connect knowledge with book knowledge to obtain relatively complete knowledge, and can cultivate students' independent exploration ability, experimental operation ability and scientific research interest. It is already an indispensable condition for improving t...
