Centripetal force tester

Abstract

The invention discloses a centripetal force tester, which comprises a support rod, the upper and lower sides of the support rod are provided with card slots, the outer wall of the support rod is sleeved with a fixing device, and the bottom end of the fixing box is installed with An upper assembly plate, a lower assembly plate is installed on the bottom end of the upper assembly plate, a slide bar is installed on the top end of the lower assembly plate, and a force sensor is installed on the bottom end of the lower assembly plate. In this centripetal force tester, when it is necessary to adjust the position of the force sensor, pull the fixed box to the left or push the fixed box to the right, squeeze the stuck ball through the support rod, make the stuck ball squeeze the push rod, and the push rod presses the sliding plate, which can make the push The rod drives the slider to slide and press the spring on the concave slide plate, so that the ball enters the fixed box. When the ball reaches the position of the adjacent groove, the spring springs the sliding plate, so that the push rod drives the ball back into the groove Inside, the fixed box can be firmly fixed on the pole, and the fixed box can be pulled to a suitable position on the pole according to the needs of use.

Description

technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a centripetal force experimental instrument. Background technique [0002] Various physical phenomena that occur in nature are often intricate, so in many cases, the factors that affect the object of physical research are not single, but a variety of factors intersect and work together. In order to find out the reasons and laws of things change , it is necessary to turn the problem of multiple factors into a problem of multiple single factors. By separately controlling the change of one of the multiple factors, we can study the influence of this factor on things, study them separately, and finally solve them comprehensively. This method is called The controlled variable method is often used in the teaching of physical experiments, such as the teaching experiment of centripetal force, such as the patent No. 201521063164.5, including the base, and the centripetal f...

[0002] Various physical phenomena that occur in nature are often intricate, so in many cases, the factors that affect the object of physical research are not single, but a variety of factors intersect and work together. In order to find out the reasons and laws of things change , it is necessary to turn the problem of multiple factors into a problem of multiple single factors. By separately controlling the change of one of the multiple factors, we can study the influence of this factor on things, study them separately, and finally solve them comprehensively. This method is called The controlled variable method is often used in the teaching of physical experiments, such as the teaching experiment of centripetal force, such as the patent No. 201521063164.5, including the base, and the centripetal force experiment instrument also includes the first pole and the second pole , DC motor, photoelectric gate, weight plate, weight, fixed wheel shaft and force sensor, although the verification of the centripetal force formula is realized, the connection structure is relatively simple, and the cost is low, but the force sensor cannot be replaced after damage, and it is inconvenient to use. The position of the force sensor is adjusted by fixing the screw, and the fixing screw is often easy to loosen, causing the force sensor to shift when the pole moves, which affects the accuracy of the experiment
