科院本科畢業(yè)論文：剛體平面運動質(zhì)心分析及其應(yīng)用(完整版)
【正文】 加方式不唯一。 界定剛體標(biāo)準(zhǔn) 物體受力必然形變，剛體界定的原則是形變不大，即可視為剛體。 [1] 本文脈絡(luò) 本文先分別對剛體模型、角動量及力矩的引入加以論述并且作為第五部分剛體基點選擇、剛體模型變換條件及質(zhì)心為合力 等效作用點內(nèi)容的鋪墊，以此貫通剛體平動部分物理圖像；應(yīng)用部分悠悠球為實例，分析其最基本運動情況的動力學(xué)過程。Application part in the yoyo as an example,analyses the movement principle. Key words :rigid body center of mass plane parallel motion. 1 目 錄 摘 要 ..............................................................................................................................
