Abstract

The invention discloses a free falling body gravity acceleration measuring instrument, and relates to the technical field of teaching experiment facilities. The measuring instrument includes a bottomplate, the two sides of the top of the bottom plate are respectively and fixedly connected with supporting frames, a mounting plate is fixedly connected to the top parts of the supporting frames, anda mounting box is fixedly connected to the top of the mounting plate, a wire winding box is fixedly connected to the top of the inner wall of the mounting box, a worm is rotationally connected betweenthe two sides of the inner wall of the wire winding box through a bearing, one end of the worm penetrates through the wire winding box and extends to one side of the wire winding box. According to the free falling body gravity acceleration measuring instrument, the situation that the measuring instrument requires the experimenter to manually pick up the experimental ball after the end of an experiment, re-put the ball to the highest point and wait for the next experiment can be avoided, the automation degree of the measuring instrument is greatly improved, the working burden of experimentersis reduced, so that the experiment ball can be automatically retracted rapidly and conveniently, so that the measurement work of the gravity acceleration of the free falling body by an experimenter isgreatly facilitated.

Description

technical field [0001] The invention relates to the technical field of teaching experiment facilities, in particular to a free-fall gravity acceleration measuring instrument. Background technique [0002] Free fall gravitational acceleration measurement is a very important technology, which occupies an important position in scientific research and middle school physics experiment teaching. The measuring instrument is to calculate the gravitational acceleration according to the formula h=v0t+gt2 / 2 by measuring the distance and time of free fall motion Size, free fall gravitational acceleration measuring instrument is mostly made of support, electromagnet, small iron ball, three photoelectric gates, electronic timer at present. Before the experiment, adjust the vertical of the bracket, and install the photoelectric gate at the upper, middle and lower positions of the bracket. During the experiment, use the electromagnet to control the ball to do free fall, and measure the fall...
