Abstract

The invention relates to a demonstrating device, in particular to a demonstrating device for throwing in physics education. The demonstrating device for throwing in physics education is simple and easy to understand, and can solve technical problems. The demonstrating device comprises a base, sliding bushes, a sliding rod, a first connecting rod, a swinging base, a second connecting rod, a third support, a motor and others; a first support is fixedly connected to the left side above the base, a rocker is connected rotatably to the first support, a throwing spoon is fixedly connected to the left end of the rocker, and two second supports are fixedly connected to the base and located on the right side of the first support. The demonstrating device demonstrates throwing in physics education,buffers the throwing spoon, gets a thrown ball, and has the advantages of being convenient and safe to use, simple in operation, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to a demonstration device, in particular to a throwing demonstration device for physics education. Background technique [0002] Throwing is a behavior in which a low hand or a high hand throws a relatively high arc upward when the defender is tight, and then attacks the basket. [0003] In the teaching of physics, the teacher needs to demonstrate the throwing and throwing. The existing throwing and throwing demonstrations are performed by the teacher manually to the students. The teacher's manual demonstration to the students is not only time-consuming and laborious, but also many students find it difficult to understand the process of throwing and throwing. Progress is slow, so there is an urgent need for a simple and easy-to-understand throwing demonstration device for physical education. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention overcomes the need for the teacher ...
