Embodiment Construction

[0014] 1-iron plate, 2-magnet, 3-trajectory recording paper, 4-flat throwing track, 5-oblique throwing track, 6-liquid injector, 7-water outlet, 8-water outlet pipe, 9-shell, 10 -Syringe outlet, 11-Syringe outer cylinder, 12-Syringe push rod, 13-Roller, 14-Extension spring, 15-Press plate

[0015] As shown in Figures 1 and 2, the present invention provides a device capable of recording the trajectory of flat throwing and oblique throwing. The motion track 5 and the liquid injector 6 are formed. When demonstrating the flat throwing motion, the trajectory recording paper 3 is laid on the iron plate 1, and the flat throwing motion track 4 is installed on the iron plate 1. A liquid injector 6 is installed on the top, and a magnet 2 is adsorbed on the bottom; when demonstrating the oblique throwing movement, it is only necessary to replace the flat throwing motion track 4 with the oblique throwing motion track 5, and the connection of other equipment and the demonstration of the fl...

Abstract

The utility model relates to a device which can record the trajectories such as level throw and obligue throw, belonging to the experimental device field, which comprises an iron plate (1), a lodestone (2), a piece of trajectory record paper (3), a level-throw motion orbit (4), an obligue-throw motion orbit (5) and a liquid injector (6). The utility model has the advantages of simple structure and convenient usage; with the device, the student can research, observe and analyse the trajectories of object motion more intuitively and more clearly; thus the device is suitable for experiments of schools and research institutions with very strong practicability.

Description

technical field [0001] The invention belongs to the field of experimental devices, in particular to a device capable of recording the trajectory of flat and oblique throws. Background technique [0002] In the school's course of teaching physical motion trajectory, physical kinematics has two important experiments: flat throwing motion and oblique throwing motion, which need to show the trajectory of the object's motion, and use the trajectory to verify some laws of flat throwing motion. However, due to the limitations of the experimental equipment, it is impossible to accurately express the trajectory of the flat parabola and oblique throw, which makes it difficult for students to vividly understand the experiment. Although there are many methods at present, they are not ideal. If we can design an experimental device that can demonstrate the motion of flat throwing, and can clearly show the whole experimental process, it will bring great benefits to improve students' learni...
