Experimental device for studying uniform variable speed linear motion

Abstract

The invention discloses an experimental device for studying uniform variable speed linear motion. The device includes a table body and an experimental unit, the experimental unit comprises an experimental board, supporting legs, a fixing frame, a connecting frame, a pulley, a vehicle body, a buckle ring, a connecting rope, a tension sensor, a hook, a paper tape and a dotting timer; the supportinglegs are vertically fixed at the four corners of the bottom of the experimental board, the fixing frame is fixed on the supporting legs at one end of the experimental board, and the supporting legs are fixedly connected with the table body through the fixing frame, and the other end of the bottom of the experimental board is in sliding connection with the connecting frame, the experimental board is fixedly connected with the table body through the connecting frame, the pulley is vertically mounted at one end of the top of the experimental board, the vehicle body is arranged on one side, located on the pulley, of the experimental board. According to the experimental device is used for studying uniform variable speed linear motion, the supporting legs are fixed at the bottom of the experimental board, the height of the experimental board can be adjusted through the supporting legs, so that teaching of the teacher can be facilitated and the experimental board can be conveniently fixed through the connecting frame and the fixing frame.

Description

technical field [0001] The invention relates to the technical field of teaching experiments, in particular to an experimental device for studying uniformly variable linear motion. Background technique [0002] Objects moving in a straight line, if the change of speed is equal in equal time, this kind of motion is called uniform linear motion. It can also be defined as: the motion along a straight line with constant acceleration is called uniform linear motion. [0003] The existing experimental equipment for constant speed and linear motion is relatively large. When the lecturer conducts this experiment, he needs to place the experimental board on the desk, but the height of the existing desk is low, which is not conducive to the teacher's lecture, and the existing All the experiments used are weights, and weights are not conducive to fixing, and using other objects is not conducive to detecting specific pulling force values. Contents of the invention [0004] The object...
