摘要:這篇論文是把一種測(cè)量重力加速度的新方法（即雙線擺測(cè)量重力加速度）與單擺測(cè)量重力加速度進(jìn)行比較研究。首先進(jìn)行雙線擺測(cè)量實(shí)驗(yàn)，通過控制變量，選長(zhǎng)度相同的兩條擺線，固定兩懸點(diǎn)之間的距離，利用游標(biāo)卡尺測(cè)出小球的直徑，從而計(jì)算出小球的半徑，進(jìn)一步計(jì)算出雙線擺的等效擺長(zhǎng)，即等效擺長(zhǎng)為擺球中心到兩個(gè)懸點(diǎn)中心的垂直距離，測(cè)量過程中通過調(diào)節(jié)兩個(gè)懸點(diǎn)在米尺上的九個(gè)不同位置，來測(cè)出九種不同位置下擺球連續(xù)擺動(dòng)30個(gè)周期所用的時(shí)間，對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行誤差分析，求出利用雙線擺測(cè)量的最接近理論值的重力加速度。接下來則是利用單擺進(jìn)行實(shí)驗(yàn)，測(cè)量九種不同擺線長(zhǎng)情況下，每種擺長(zhǎng)下擺球連續(xù)擺動(dòng)30個(gè)周期所需要的時(shí)間，然后算出單擺測(cè)量的重力加速度，并對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行誤差分析，記錄單擺最佳測(cè)量時(shí)所測(cè)重力加速度，最后對(duì)單擺和雙線擺的最佳實(shí)驗(yàn)結(jié)果進(jìn)行科學(xué)分析比較，比較哪種情況更加接近理論值，然后得出結(jié)論，結(jié)合實(shí)驗(yàn)中得到的結(jié)論和發(fā)現(xiàn)的問題，可以設(shè)計(jì)出更好的實(shí)驗(yàn)方案。 關(guān)鍵詞：雙線擺；單擺；重力加速度；等效擺長(zhǎng)；周期
ABSTRACT:This essay is a kind of new method of measuring gravity acceleration (i.e. double pendulum measurement gravity acceleration) and single pendulum measurement gravity acceleration comparative studies. First, by double pendulum measurement control variables, choose the length of the same two cycloid, fixed the distance between the two suspended points, measured by the diameter of vernier caliper, and small balls, calculated the radius of the double pendulum further calculated long, namely equivalent equivalent place for pendulum ball placed long to center of vertical suspension point center two distance, measured by adjusting the two suspended during the nine points on the meter scale beside different position, to measure the nine different position hem swinging 30 cycle ball continuous time used, error analysis of experimental results using double pendulum, ask out the most close to the theoretical value measurement of gravity acceleration. The next simple pendulum is to use test, measurement nine different cycloid long cases, each place long tail ball swing 30 cycle for the time required, and then calculate the gravity acceleration simple pendulum measurement, and the experimental results for error analysis, record when measuring the best single pendulum measured gravity acceleration and evolvement of single pendulum, and finally the best experimental results set scientific analysis comparison, more what is more close to the theoretical value, then draw the conclusion, combining experiments the conclusion and the problems found, can design a better experiment scheme. Keywords: Double pendulum; Single pendulum; Gravity acceleration; Equivalent place long; cycle |
