Problems solved by technology

[0002] The current technical level of the demonstration instrument: the first type of flat throwing and vertical falling instrument only compares the movements of flat throwing and vertical falling, and is seriously lacking in one of the uniform motions for simultaneous comparison experiments, and the comparison method is extremely unstable due to the comparative sound method and non-obvious bad methods; the second instrument either only captures a certain transient state in the above-mentioned movement process and records the traces correspondingly, and the experimental process results obtained are more authentic and credible

However, the accuracy of the experimental results is low, and the follow-up exploration and processing of the experiment are more cumbersome and many other unreasonable experimental weaknesses; Movement displacement cannot be effectively and directly captured and measured, that is, the experimental process of the movement lacks a sense of reality or lacks fidelity, or although there is an experimental method to simultaneously determine time and displacement through corresponding displacement sensors, it can only The indirect experimental observation and processing through the computer screen is less in line with the above-mentioned teachers and students' experimental exploration of psychological laws and many other major shortcomings; more importantly, the current state of technology is relatively good: the combination of sensors and computer software can only solve straight-line problems. Direct measurement of parameters related to motion, but the parameters and process of the above-mentioned curved motion cannot be directly measured and displayed in real image, that is, the curved motion can only be traced on the computer screen first, and then displayed on the computer screen Carrying out indirect measurement and analysis of the curve movement is decomposed into two straight lines, and then exploring it is actually a simulation demonstration experiment.

What's more, it is required to carry out the experimental operation, observation, comparison, quantitative measurement and other methods of horizontal throwing, uniform speed, and vertical fall at the same time. This is currently the only way to find a demonstration experimental instrument that meets the above requirements
