Embodiment

[0014] 1) The remote control car is a kind of toy car.

[0015] 2) The front springboard is a wooden plank with a length of 80cm and a width of 10cm, and its pillars are wooden columns with a height of 17cm.

[0016] 3) The rear springboard is a plank with a length of 60 cm and a width of 10 cm, and its pillars are wooden columns with a height of 9 cm.

[0017] 4) The model of the Great Wall is a cuboid plank with a height of 8cm and a picture of the Great Wall on it.

[0018] 5) Adjust the distance between the front and rear springboards to ensure that the remote control car just flies over the Great Wall model; place the remote control car on the horizontal part of the front springboard, point the front of the car at the direction of the Great Wall model, and control the car through the remote control to accelerate it up to Two springboard gaps are spent, and the gap is leaped.

Abstract

The invention discloses an experimental device of simulating the leaping over the Great Wall, which comprises a remote control trolley, a remote controller, a front spring-board, a Great Wall model, a rear spring-board and a column, wherein the front spring-board and the column are fixed into a whole through a screw, the rear spring-board and the column are fixed into a whole through the screw, and the Great Wall model is placed between the front spring-board and the rear spring board. The experimental device has the advantages that the structure is simple, adventurous and exciting, and the learning interest of students can be easily aroused.

Description

Technical field: [0001] The invention relates to a physical experiment device, in particular to a simulation experiment device for leaping over the Great Wall used in physics teaching in high school and junior high school. Background technique: [0002] In high school and junior high school physics teaching, every time when "inertia" is mentioned, the general teachers often show the video clips of "Speeding over the Great Wall" to the students to introduce the concept of inertia or let the students analyze the principle that the flying car can cross the Great Wall . This phenomenon is thrilling and exciting, and it is easy to stimulate students' interest in exploring problems. It is a good situation that is rarely encountered in teaching. However, the above scheme lacks real feelings and has not yet achieved the desired effect. Invention content: [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a simple, safe and ex...
