Galileo cant demonstrator

Abstract

The invention discloses a Galileo cant demonstrator which has the advantages of remarkable phenomenon, simple structure and convenience for self-production. The Galileo cant demonstrator is necessary in study of Newton first law. In multiple years, a number of physics laboratories in middle schools do not have the Galileo cant demonstrator, and it is difficult to buy the Galileo cant demonstrator. The reasons for the problems are that firstly, a gliding trolley or ball cannot be guaranteed to run in the same vertical surface; and secondly, inclined surfaces at two sides are not connected smoothly, thus the trolley or ball loses a large amount of energy at the bottom end, large experimental errors are caused, the phenomenon are not obvious, and the abstract theory is more difficult to understand. The Galileo cant demonstrator adopts a PVC (polyvinyl chloride) wire clamping groove upper cover as the guide rail, and a glass ball instead of the moving trolley, therefore, the experimental phenomenon are extremely obvious, the whole device has the advantages of simple structure, convenience for drawing of materials, convenience for self-production or batch production, and capability of filling the gap of the apparatus in laboratories quickly. In addition, the Galileo cant demonstrator can be used for qualitative research of the theory of conversion of kinetic energy and gravitational potential energy of an object.

Description

(1) Technical field [0001] The biggest highlight of this set of "Galileo inclined plane demonstrator" is that the upper cover of the PVC cable slot is used to make the track. It can not only ensure the smooth rolling of the ball along the vertical plane, but also bend the arc at will, with little energy loss, and the experimental phenomenon is obvious. On the basis of this experiment, if the "Newton's first law" is further derived, it will be a matter of course and a matter of course. [0002] Utilizing this set of devices can also qualitatively study the theory of the mutual transformation of kinetic energy and gravitational potential energy of objects. (2) Background technology [0003] Galileo's inclined plane experiment is the basis for deriving Newton's first law. For several years, this simple set-up was not available in many high school physics laboratories and was difficult to obtain. There are two reasons for this: first, it is difficult for the sliding car or ba...

Problems solved by technology

For several years, many high school physics labs did not have this simple set up and it was difficult to purchase

There are two reasons for this: first, it is difficult for the sliding car or ball to move in the same vertical plane; second, because the slopes on both sides are not connected smoothly, the energy loss of the car or ball at the bottom is large, It leads to large experimental errors and inconspicuous phenomena, which makes abstract theories more difficult to understand
