Horizontal projectile motion demonstration instrument with automatically-adjustable levelness

Abstract

The invention provides a horizontal projectile motion demonstration instrument with the automatically-adjustable levelness, and belongs to the field of physical experiment demonstration equipment. The instrument comprises a demonstration panel and a controller. A fixing device and a ball receiving groove are arranged on one side face of the demonstration panel. The two adjacent side edges of the outer side face are provided with a vertical rod and a horizontal rod. The vertical rod and the horizontal rod are perpendicularly arranged on the outer side face. The horizontal rod and the ball receiving ball are arranged in parallel. The two ends of the horizontal rod are provided with a first supporting foot hinged to the horizontal rod and a second supporting foot connected to the horizontal rod through a horizontal adjusting device. The controller is connected with the horizontal adjusting device. A counter weight device and an induction device are arranged inside the demonstration panel. The counter weight device is suspended on a plane parallel to the outer side face, where the ball receiving groove is formed, of the demonstration panel. The induction device comprises a first inductor and a second inductor matched with the first inductor. The demonstration instrument can automatically adjust the levelness of itself, saves time and labor, and is simple in structure and easy to operate.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of physical experiment demonstration equipment, in particular to a horizontal throwing motion demonstration instrument with self-adjustment. [0003] 【Background technique】 [0004] The experiment of flat throwing motion is one of the experimental items that must be done in physical experiments. There are a variety of flat throwing motion experimental equipment in the market. The parts of these experimental equipment are relatively scattered, and the experimenter needs to manually install each part and the equipment. Manually adjusting the level of the horizontal section of the throwing motion throwing track is time-consuming, difficult to adjust, and the adjustment accuracy is not high, which will bring human error to the experiment, resulting in inaccurate experimental results. [0005] [Content of the invention] [0006] In view of the above, it is necessary to provide a levelling self-adjusting flat throw...

[0004] The experiment of flat throwing motion is one of the experimental items that must be done in physical experiments. There are various experimental equipment for flat throwing motion in the market. Manually adjust the levelness of the horizontal section of the flat throwing track. This adjustment process is time-consuming, difficult to adjust, and the adjustment accuracy is not high. This will bring human errors to the experiment and cause inaccurate experimental results.
