Abstract

PURPOSE: An experimental apparatus for a parabolic motion is provided to control force and exactly measure a shooting angle of an object since an experiment is performed in anywhere, indoors and outdoors. CONSTITUTION: A base(10) supports a body(20). A support(11) connects the body and the base. An angle control meter(21) measures an angle of a back side of the body. A horizontality control meter(22) levels off on the middle of the body. An elasticity gear(23) controls a spring(24) and elastic force of the spring. A laser(25) and a bead(30) represent a start point for launching.

Description

포물선 운동 실험 교구 {experiment instrument for parabolic motion}Parabolic motion experiment parish {experiment instrument for parabolic motion}

본 발명은 물체의 포물선운동 및 용수철을 이용한 힘의 관계를 실험할 수 있는 실험 교구에 관한 것으로, 더욱 상세하게는 각도측정기가 있는 몸체의 각도를 조절하고 탄성 기어장치로 탄성력을 변화시켜 발사함으로서 쉽게 포물선운동과 탄성력을 이해할 수 있도록 한다.The present invention relates to an experimental teaching aid that can test the relationship between the parabolic motion of the object and the force using the spring, and more particularly, by adjusting the angle of the body with an angle measuring device and changing the elastic force with the elastic gear device to easily fire. Understand parabolic motion and elastic forces.

기존에 포물선운동을 배울 때 우리는 밖에서 직접 물체를 손으로 던져 봐야했다.When learning parabolic motion, we had to throw objects directly from the outside.

따라서 거리의 정확성이 부족하고 밖으로 나가야만 측정할 수 있다는 불편함이 있고 또한 힘을 일정하게 줄 수 없다는 치명적인 단점이 있다.Therefore, there is a lack of accuracy of the distance, the inconvenience that can be measured only to go out, and there is a fatal disadvantage that can not give a constant force.

또한 던지는 각도를 정확히 알 수 없는 불편함도 있었다.There was also the inconvenience of not knowing exactly the throwing angle.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로The present invention is to solve the above problems

몸체에 각도 조절계가 연결되어 정밀한 각도측정을 할 수 있고,An angle controller is connected to the body for precise angle measurement.

탄성 기어가 있어서 힘도 정확히 측정할 수 있게 하여 포물선 운동과 탄성력을 Elastic gears allow for accurate measurement of forces, allowing for parabolic motion and elastic force

보다 잘 이해할 수 있도록 하는 것을 목적으로 한다.The goal is to help you better understand.

상기 서술한 문제를 해결하기 위하여 몸체(20)를 지탱해주는 밑받침(10)과, 몸체(20)와 밑받침(10)을 이어주는 지지대(11),몸체 후면에 각도를 재는 각도 조절계(21), 몸체 중간에 수평을 맞추는 수평 조절계(22), 스프링(24)과 스프링의 탄성력을 조절하는 탄성 기어(23), 발사의 시작점을 나타내는 레이저(25)와 구슬(30)로 구성된다.In order to solve the above problems, the base 10 supporting the body 20, the support 11 connecting the body 20 and the base 10, the angle adjuster 21 to measure the angle on the rear of the body, the body It consists of a horizontal adjustment system 22 to level in the middle, the spring 24 and the elastic gear 23 for adjusting the elastic force of the spring, the laser 25 and the ball 30 indicating the starting point of the firing.

포물선 운동에서 제일 멀리 나가게 하는 방법은 물체를 45도로 발사하는 방법인데The farthest way out of parabolic motion is to fire an object at 45 degrees.

이론으로는 증명할 수 있지만 실험으로 정확하게 실험 할 수 있는 방법은 없었다.하지만 '포물선 운동 실험 교구' 는 실외 실내 어디서나 실험을 할 수 있고 각도도 정확하게 측정할 수 있으며 힘도 조절할 수 있어 더욱 힘과 운동을 쉽게 이해할 수 있도록 도와줄 수 있을 것이다.Although the theory can prove it, there was no way to experiment precisely, but the Parabolic Experiment Diocesan can be conducted anywhere, indoors, precisely measure the angle, and adjust the force for more force and motion. It will help you understand it.

Figure 3 is an enlarged view of the back of the experiment parishion according to the present invention.

먼저 수평 조절계(22)로 수평을 맞추고 각도 조절기(21)을 0도 로 맞춘다.First, level the horizontal adjuster 22 and adjust the angle adjuster 21 to 0 degrees.

다음 각도 조절계(21)로 원하는 각도를 맞추고 스프링(24)를 원하는 것으로 장착한 후 탄성 기어(23)를 이용하여 힘을 조절한다. 그 후 원하는 구슬(30)을 골라 구슬을 올려놓은 후 발사한다. 마지막으로 레이저(25)가 표시된 바닥으로부터 거리를 측정한다. Next, adjust the force by using the elastic gear 23 after adjusting the desired angle with the angle adjuster 21 and mounting the spring 24 as desired. Then choose the ball of your choice (30) put the ball and then fire. Finally, the laser 25 measures the distance from the marked floor.
