Problems solved by technology

[0002] Free fall experiment and simple pendulum experiment are necessary experimental courses in physics, but now, the vast majority of physics teaching uses the experiment method of free fall-dot counter, which has a large error and is not easy in the teaching process. Intuitive demonstration of experiments to students
In addition, the existing physical experiment equipment has a single usage and cannot carry out multiple experiments at the same time, so it cannot be used effectively

Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] figure 1 and figure 2 A schematic structural diagram of the gravitational acceleration experimental device provided by the embodiment of the present invention is shown together. For the convenience of description, this figure only provides the structural parts related to the present invention.

[0048] The gravity acceleration experimental device includes a box body 1, which is a sealed transparent box body with an openable upper cover. The sealed box body 1 can reduce the experimental error caused by air flow, and students can observe the experimental phenomena through the transparent box...

Description

technical field [0001] The invention belongs to the technical field of physical experiments, in particular to a gravitational acceleration experimental device. Background technique [0002] Free fall experiment and simple pendulum experiment are necessary experimental courses in physics, but now, the vast majority of physics teaching uses the experiment method of free fall-dot counter, which has a large error and is not easy in the teaching process. Provide students with an intuitive demonstration of the experiment. In addition, the existing physical experiment equipment has a single usage, cannot carry out multiple experiments at the same time, and cannot be used effectively. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the deficiencies in the prior art, provide a device that is easy to operate, can accurately measure the acceleration of gravity in two ways, has small experimental errors, and is intuitive an...
