Abstract

본 발명은 1개로 세트화 된 실험기구와 여러 개의 악세서리를 이용하여 각종 역학 실험(운동의 기록, 등속운동, 가속도 운동, 낙하운동, 관성, 힘과 속력의 변화, 빗면에 대한 실험, 도르레에 대한 실험, 중력에 대한 실험, 마찰력에 대한 실험, 마찰력에 대한 실험, 위치에너지, 에너지 보존 등)을 통합적으로 실시할 수 있는 역학 실험세트에 관한 것으로, 상세하게는 학생들이 실험시 설치를 따로 사용하는 종래의 개별적인 실험기구보다 본 발명에 의한 역학 실험세트를 사용하면, 실험 기구 설치시간을 약 70%∼80%까지 대폭적으로 단축시킬 수 있으며, 개별 실험기구의 수가 적을수록 설치시간을 줄일 수 있다.The present invention uses a set of experimental instruments and a number of accessories in a variety of mechanical experiments (recording of motion, constant velocity, acceleration, drop motion, inertia, force and speed changes, experiments on slopes, pulleys) Experiment, Gravity Test, Friction Test, Friction Test, Potential Energy, Energy Conservation, etc.). By using the dynamic test set according to the present invention rather than the conventional individual test apparatus, the installation time of the test apparatus can be drastically shortened by about 70% to 80%, and the smaller the number of individual test apparatuses, the installation time can be reduced.

또한, 실험의 내용이 다르더라도 동일한 실험기구를 사용하면 기구에 대한 생소함으로 인한 두려움이 없어져 자신있게 실험을 수행하며 흥미와 관심을 높을 수 있을 뿐 아니라 실험기구를 연속적으로 설치할 수 있으며, 또한 가속도 운동에서 개별 실험기구는 가속도의 변화 폭이 14cm/s로 변화의 폭이 본 발명 역학 실험 세트를 이용하는 경우 1.5cm/s 여서 정밀도가 열 배나 향상된다.In addition, even if the contents of experiments are different, using the same experimental instruments eliminates the fear of unfamiliarity of the instruments, so that the experiments can be performed with confidence, interest and interest can be increased, and the experimental instruments can be continuously installed. In the individual test apparatus, the change width of the acceleration is 14 cm / s, and the width of the change is 1.5 cm / s when using the dynamic test set of the present invention, so that the precision is improved ten times.

본 발명에서 부대장치를 개발한다면 다른실험을(예를들어 마찰력 실험, 위치-운동에너지의 실험 등)도 할 수 있을 것이다.If the auxiliary device is developed in the present invention, other experiments (for example, a friction force test, a position-kinetic energy test, etc.) may be performed.
