Abstract

The invention provides a projectile motion experimental instrument and an experimental instrument system. The projectile motion experimental instrument comprises a magnetic ball body, a throwing device, a display panel, a ball receiving groove and a base. The display panel comprises a display screen, a sensing circuit and a controller. The sensing circuit comprises a plurality of magnetic sensors and a scanning circuit board. The plurality of magnetic sensors are arranged on the scanning circuit board at a preset interval. After the magnetic ball body is thrown out of the throwing device, the magnetic ball body conducts the parabolic movement at the front part of the display panel. During the parabolic movement, the magnetic ball body triggers the conduction of magnetic sensors at corresponding positions of the sensing circuit. The scanning circuit board sends the position signals of conducted magnetic sensors to the controller. The controller is used for sending a display signal to the display screen according to the position signals of conducted magnetic sensors, so that the display screen can display the motion track of the magnetic ball body in real time. According to the technical scheme of the invention, the projectile motion experimental operation is simple and efficient. Furthermore, the teaching effect of the projectile motion experiment is improved.
