The invention discloses a physical gravity experiment simulation device. One end of a supporting base plate is provided with a fixed substrate, and the upper part of the fixed substrate is fixedly provided with an elliptical earth model. The interior of the elliptical earth model is provided with a permanent magnet in an inset manner, and a distance sliding rail is disposed on the supporting base plate. A vertical rod is fixed in a slideway of the distance sliding rail in a mode that a fixed rubber wheel can slide. The upper end of the vertical rod is connected with a bottom end through a telescoping part. The upper end of the vertical rod is fixedly provided with a pallet which is parallel to a plane where the supporting base plate is located. The upper part of the pallet is provided with a spring fixing rod which is fixed on the vertical rod. One end of the spring fixing rod is connected with one end of a spring, and the other end of the spring is connected with an experiment ball. One end, connected with the experiment ball, of the spring is fixedly provided with an attractive force pointer. The experiment ball is fixedly provided with a latitude pointer. The upper part of the attractive force pointer is provided with an attractive force ruler fixed on the vertical rod. The attractive force ruler is provided with force graduation lines. The experiment ball is made of iron. The device can simulate the gravity generation principle of the earth, can achieve the research of the factors affecting the size of gravity, and greatly improves the teaching efficiency.
Description
technical field [0001] The invention relates to a device in the field of physics teaching, in particular to a physical gravity experiment simulation device capable of simulating the principle of the earth's gravity and studying factors affecting the magnitude of gravity. Background technique [0002] The force that an object receives due to the attraction of the earth is called gravity. The object that exerts the force of gravity is the center of the earth, and the direction of gravity is always vertically downward. In physics teaching, the known knowledge is used to teach students that the gravity of an object is proportional to the mass of the object. The calculation formula is: G=mg, g is the proportional coefficient, about 9.8N / kg, and the gravity varies with the latitude The magnitude of gravity also changes with the height of the object from the earth. In traditional teaching, only the influencing factors of gravity are only instilled, and the lack of experimental equ...
