High school physics horizontal projectile motion device

Abstract

The invention provides a high school physics horizontal projectile motion device, which comprises a base. A box body with a front opening is arranged above the top surface of one side of the base, a plurality of fixing blocks are fixedly installed on the bottom surface of the box body, and a buffer groove is formed at the bottom surface of the fixing block. A buffer rod is fixedly arranged at thetop surface of one side of the base, and the upper end of the buffer rod is located in the buffer groove. A door body is arranged in front of the box body, and the door body can shield the front opening of the box body. The door body is hinged to the box body, and transverse plates are fixedly arranged at the lower ends of the two sides inside the box body. The top surface of the transverse plateis provided with an arc-shaped groove, two first through holes are formed in one side of the interior of the box body, and one first through hole is communicated with the interior of the arc-shaped groove. The box body with an opening at the top surface is fixedly arranged on one side of the box body, second through holes are formed in the two sides of the interior of the box body, and one of thefirst through holes is communicated with the interior of one of the second through holes. When vibration is generated in the working process, the buffer rod is buffered in the buffer groove, so that the device can play a role in buffering and damping the device, so that the device is more stable in the working process.

Description

technical field [0001] The invention belongs to the field of high school physics teaching devices, in particular to a high school physics flat throwing exercise device. Background technique [0002] The object is thrown along the horizontal direction with a certain initial velocity. If the object is only affected by gravity, this kind of motion is called flat throwing motion. When the existing high school physics flat throwing device is in use, the operator needs to first coat the surface of the steel ball with graphite before conducting the experiment. This is easy to get the operator to have graphite in his hand, which affects the normal class. During the demonstration, the steel ball It is manually configured. During the demonstration, the steel balls roll down everywhere. After the demonstration, it needs to be collected manually, which is inconvenient to use. Contents of the invention [0003] The invention provides a high school physics flat throwing exercise device...
