본문 Discover Free Fall System Purpose Understanding the movement of free falling objects, and measuring value of the acceleration of gravity Theory The object gets gravity when it falls around the surface of the earth. F=GMm/r² (G: universal gravitation constant, M: mass of the earth, r: distance between the earth and object) Whenever the distance from the surface of the earth to the object is too short compared to radius of the earth R, the distance in formula can be used rR and the gravity F can be F = GMm/r² = mg G in formula above is called acceleration of gravity, its value is 9.8㎨, and it is constant value regardless of mass. The equation of motion of a falling object around the surface of the earth is mg=m(d2x/dt2) From this formula, distance of falling (h) is given when the time is t h= gt2/2 So if you measure the distance of falling (h) and the time of falling (t), you can get the acceleration of gravity (g) Equipments Drop box assembly : Drop box, Control box, AC adapter, Cable 하고 싶은 말 좀 더 업그레이드하여 자료를 보완하여, 과제물을 꼼꼼하게 정성을 들어 작성했습니다. 위 자료 요약정리 잘되어 있으니 잘 참고하시어 학업에 나날이 발전이 있기를 기원합니다 ^^ 구입자 분의 앞날에 항상 무궁한 발전과 행복과 행운이 깃들기를 홧팅 키워드 실험, 일반, 실험레포트, 물리학, 실험레, 포트
