Problems solved by technology
[0002] In physics teaching, when it comes to the interaction between kinetic energy and elasticity and the transformation of gravitational potential energy, due to the lack of special teaching aids for demonstration, it can only be explained through theory. This kind of complete language expression cannot be fully understood by students, especially in primary schools. Among the students, due to their young age and poor comprehension ability, they cannot fully understand

The invention provides a kinetic energy and elasticity conversion demonstrator for teaching. The kinetic energy and elasticity conversion demonstrator used for teaching is provided with an inclined sliding plate above a bracket, a spring is installed on the plate surface of the lower end of the inclined sliding plate, and the other end is equipped with a high end. Heavy Duty Roller. When in use, kinetic energy is generated by the downward sliding of the heavy roller, and an elastic return force is generated after encountering the top force of the spring, thereby showing the mutual conversion of the two forces.
Description
technical field [0001] The invention relates to a demonstrator for teaching, in particular to a demonstrator for teaching kinetic energy and elastic conversion. Background technique [0002] In physics teaching, when it comes to the interaction between kinetic energy and elasticity and the transformation of gravitational potential energy, due to the lack of special teaching aids for demonstration, it can only be explained through theory. This kind of complete language expression cannot be fully understood by students, especially in primary schools. Among the students, due to their young age and poor comprehension ability, they cannot fully understand. Contents of the invention [0003] The invention provides a kinetic energy and elasticity conversion demonstrator for teaching, which can demonstrate the mutual conversion of kinetic energy and elasticity through gravitational objects. [0004] The present invention includes a spring, and the technical solution adopted is th...
