Description
technical field [0001] The invention belongs to the technical field of learning appliances, and in particular relates to a friction demonstration device for physics learning. Background technique [0002] At present, in the existing physical experiments, the testing experiments of tension and gravity are all tested and recorded separately through a single test equipment. The functions of each test equipment are relatively single. The accuracy brought errors, in addition, a single test equipment also greatly reduced the students' interest in learning. Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a friction demonstration device for physics learning that can intuitively demonstrate that the moving speed of an object is affected by friction. [0004] The present invention is achieved through the following technical solutions: [0005] A friction demonstration device for physics learning, including a b...
