Abstract

The invention relates to the field of physics teaching, in particular to a physical projectile experiment demonstration device. The physical projectile experiment demonstration device comprises a base, a glass supporting plate and a vertical support, wherein the glass supporting plate is vertically fixed on the base and is transparent; the vertical support is fixed on the base, is positioned on the left side of the glass supporting plate and is used for enabling a fixed sliding track to slide; a first electromagnet is fixed at the top end of the sliding track; an infrared photoelectric sensor and a speed sensor are arranged at the tail end of the sliding track; a chute is formed in the base; infrared photoelectric sensors are uniformly arranged in the chute; a stroboscopic camera is arranged at the rear of the glass supporting plate; a second electromagnet with an infrared photoelectric sensor fixed at the bottom is slidably fixed on the glass supporting plate; a display screen is fixed on the right side of the glass supporting plate; a central processing unit is arranged in the base, and is electrically connected with the infrared photoelectric sensors, the speed sensor, the stroboscopic camera, the display screen and a clock circuit respectively; and the display screen displays movement tracks during horizontal projectile motion and free dropping and other data so as to facilitate observation and calculation; and good learning effect is achieved.

Description

technical field [0001] The invention relates to the field of physics teaching, in particular to a demonstration device for physics projectile experiments. Background technique [0002] The projectile experiment, as a basic physics experiment, has always been the focus of the physics teacher when teaching, but it cannot be explained vividly in the classroom, so it is necessary to use professional experimental equipment. However, the existing projectile experimental equipment has a relatively simple structure. , the object falls quickly, and students cannot describe the trajectory of the projectile, which leads to poor teaching effect and cannot meet the requirements of use. Therefore, it is necessary to optimize and upgrade the existing teaching equipment to solve the above problems. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides a physical projectile experiment demonstration device. [0004] The specific technic...
