Description

A model vehicle experience apparatus that performs non-motorized driving using gravity

The present invention relates to a model vehicle experience apparatus that performs non-motorized driving using gravity, and more particularly, understands the principles of physics such as speed while driving the model vehicle along a running path of a roller coaster structure that can be changed arbitrarily and plays a game. It relates to a model vehicle experience apparatus that performs non-motorized driving using gravity that can be experienced while enjoying the vehicle.

Physics, which elementary school students and middle school students usually encounter, is basic and contains a lot of very important courses to have a basic understanding of science.

Among them, if you do not understand the energy-related laws such as potential energy and kinetic energy accurately and rely only on memorization, you lose interest in the increasingly complex laws.

After all, although some experimental tools have appeared to help the understanding of these early physics studies, there is no way to help the understanding based on the results generated by all students assembling and experimenting themselves.

In addition, there are many learning materials for battery and electronic experiments using electronic components, but there are not enough teaching materials that can stimulate interest through both skin-to-skin experiments and play about the basic energy laws.

In this way, toys, game equipment, or amusement equipment are mainly made for interest, and although some of them are produced to achieve learning effects along with the achievement of their original purpose, in conventional equipment, high-level such as play effects and natural laws, etc. It is not easy to achieve a scientific learning effect.

This is because the scientific learning effect is lowered in order to increase the play effect, and the play effect is lowered in order to increase the scientific learning effect.
