Abstract: The measurement of accelerated velocity has a practical meaning in quantifying changes of moving state, having various quantitative types in cross-disciplinary approach. This study proposed a simple method to measure the accelerated velocity by using a set of simple equipment, tracking the changes of strained conditions of mercury column in U-tube, and quantifying the change of moving state of the measured object, and theoretically discussed multiple applications of the device in engineering. Meanwhile, an electrified measuring method was proposed based on the electro-mechanical sensor. The device has such advantages as simple design, low cost, convenient to be assembled and disassembled, providing examples for experimental teaching, research and engineering test in an intuitively understandable manner by designing new test methods with the help of existing resources.
