The invention relates to a demonstrator of a solar system celestial bodies motion model for physics teaching, and belongs to the field of physics classroom experimental instrument design in middle school. An object of the present invention is to provide a teaching device for demonstrating the motion of a solar system celestial body in a physics class of a middle school. The device consists of fourparts: the power part, the planet model part, the base support part and the starry crust part. The device demonstrates that eight planetary models of the solar system revolve around a solar model. The speed of rotation varies from fast to slow, depending on the actual speed of Mercury to Neptune. The device can simulate the movement of cosmic objects from the Earth's perspective and display images on a display screen. The invention solves the problems of the motion and the velocity difference of each planet in the solar system celestial body motion model and develops a simulation technology for viewing the universe from a human perspective in the solar system model. The device can make the abstract knowledge of celestial motion and gravitational aerospace knowledge in physics class becomevivid. Specifically, it is helpful for students to observe, learn and understand the motion of celestial bodies.
Description
technical field [0001] The invention belongs to the design field of middle school physics classroom experiment instruments, in particular to a physics teaching device used in physics classrooms to demonstrate solar system planetary motion experiments. Background technique [0002] From the treatises of the famous ancient Greek scientist Archimedes, we know that Aristarchus once created a heliocentric universe model, which is based on the following five concepts: The sun and fixed stars do not move ; the earth revolves around the sun; the earth's orbit is circular; the sun is at the center of the circle; fixed stars are extremely far from the sun and the earth. Aristarchus believed that because the earth revolves around the sun once a day, people on earth have the impression that the sky revolves around the earth, so he obviously understood that the earth is spherical. Aristarchus also believed that if the planets, including the earth, revolve around the sun, and the sun doe...
