Problems solved by technology

[0003] In middle school physics teaching, the pulley block part is not easy for students to master. During the explanation process, the teacher draws cumbersome pulley block diagrams on the blackboard to explain, but for students who have no life experience, if they want to understand the principle, and building a physical model in the brain is not an easy task

Abstract

The invention discloses a pulley for physics teaching. The pulley comprises a base (1), a frame (2), a fixed pulley (3), a movable pulley (4), a large weight (5), a small weight (6), a mooring rope (7), sliding blocks (8) and a surveyor pole (9); the frame (2) is arranged on the base (1); the surveyor pole (9) is arranged on the frame (2); a plurality of sliding blocks (8) are arranged on an upper frame (10) at the top of the frame (2); the fixed pulley (3) is arranged in a manner that the sliding blocks (8) on the upper frame (10) are connected with the mooring rope (7); the long mooring rope (7) is connected to the sliding blocks (8) on the other side of the upper frame (10); the mooring rope (7) winds around the movable pulley (4) and the fixed pulley (3); the small weight (6) is connected to the tail end of the long mooring rope (7); and the large weight (5) is connected to the movable pulley (4). The pulley for physics teaching is simple in structure; when a teacher explains physics pulley block knowledge, teaching is visual, and students can conveniently understand and master the pulley block knowledge.

Description

technical field [0001] The invention relates to the field of teaching tools, in particular to a pulley for physics teaching. [0002] Background technique [0003] In middle school physics teaching, the pulley block part is not easy for students to master. During the explanation process, the teacher draws cumbersome pulley block diagrams on the blackboard to explain, but for students who have no life experience, if they want to understand the principle, And building a physical model in the brain is not an easy task. [0004] Contents of the invention [0005] Aiming at the existing deficiencies, the purpose of the present invention is to provide a pulley for physics teaching. [0006] In order to achieve the above object, the present invention realizes a kind of pulley for physics teaching through the following technical scheme, comprising a base, a frame, a fixed pulley, a movable pulley, a heavy object, a small weight, a cable, a slide block, and a pole. There i...
