平行四邊形定則的原理？

1、平行四邊形定則是數學(xué)科的一個(gè)定律。兩個(gè)向量合成時(shí)，以表示這兩個(gè)向量的線(xiàn)段為鄰邊作平行四邊形，這個(gè)平行四邊形的對角線(xiàn)就表示合向量的大小和方向，這就叫做平行四邊形定則（Parallelogram law）。

2、驗證互成角度的兩個(gè)力合成時(shí)的平行四邊形定則。

平行四邊形定則的原理？

這是力的合成的一個(gè)經(jīng)驗原則，根據實(shí)驗分析得知兩個(gè)力的合力如果用兩條線(xiàn)段表示，那么以這兩條線(xiàn)段為邊的平行四邊形的對角線(xiàn)的大小等于合力大小，方向等于合力方向，所以后來(lái)在求合力時(shí)都很據這個(gè)原則。
