[0001] The utility model relates to the technical field of physical horizontal throwing experiments, in particular to a horizontal throwing experiment device that is convenient for recording data. Background Art

[0002] Projectile motion is the motion of a projectile with an initial velocity in the horizontal direction. It means that an object is thrown with a certain initial velocity. When the air resistance is negligible, the object moves only under the action of gravity. Projectile motion is required knowledge for high school students. In high school physics classes, students are required to personally conduct projectile experiments on the experimental device and calculate the initial velocity of the object in order to deepen their understanding of projectile motion. With the continuous development of science and technology, the experimental device is constantly being improved.

At present, due to improper operation by students during the experiment, the balance of the device is easily broken, and students cannot observe whether the device is horizontal at any time, and it is not convenient to change the initial velocity of the falling steel ball. When students record the motion trajectory of the steel ball, they need to observe the motion trajectory of the steel ball with their naked eyes, resulting in large experimental errors. However, the device cannot adjust the overall angle of the device when in use, and its practicality is relatively low; when the device is in use, the device cannot adjust the falling angle and length of the object during the initial movement. Therefore, there is an urgent need for a horizontal projection experimental device that is convenient for recording data in the market. Utility Model Content
