Problems solved by technology
The point where gravity acts on an object is called the center of gravity. In some teaching, it is necessary to simulate the physical gravity experiment, including whether the physical gravity is related to the height. However, the existing physical gravity experiment simulation device is not easy to adjust to different heights. Carry out experiments, can not meet the needs of users

The invention discloses a physical gravity experiment simulation device. The device comprises an experimental frame on which a mounting block is arranged, wherein the mounting block is of a hollow structure and sleeves the experimental frame in a sliding manner; a fixing rod is fixedly mounted at one side of the mounting block, and a mounting chamber is formed in the mounting block; a positioningrod is mounted in the mounting chamber in a sliding manner; connecting rods are rotatably connected to two sides of the positioning rod; the connecting rods are obliquely arranged, and a sliding blockis rotatably connected to one end, far away from the positioning rod, of each connecting rod; two sliding grooves are symmetrically formed in the inner wall of one side, close to the fixing rod, of the mounting chamber; a mounting rod is welded on the inner walls of two sides of the two sliding grooves, and one end, far away from the corresponding connecting rod, of each sliding block extends into the corresponding sliding groove and sleeves the mounting rod in a sliding manner. The device is simple in structure, convenient to use, and capable of being adjusted to reach different heights forexperiment, and thus the use demands of users can be met.
Description
technical field [0001] The invention relates to the technical field of gravity experiments, in particular to a physical gravity experiment simulation device. Background technique [0002] The force exerted on an object by the attraction of the earth is called gravity. The force object of gravity is the center of the earth. The direction of gravity is always straight down. The magnitude of the gravity on the object is proportional to the mass of the object. The calculation formula is: G=mg, g is the proportional coefficient, the gravity is about 9.8N / kg, and the gravity changes with the latitude, which means an object with a mass of 1kg The gravity received is 9.8N. The point where gravity acts on an object is called the center of gravity. In some teaching, it is necessary to simulate the physical gravity experiment, including whether the physical gravity is related to the height. However, the existing physical gravity experiment simulation device is not easy to adjust to ...
