✔ 最佳答案
Newton's Laws 只需要簡單既vector技巧.只要識得2D vector就夠
例如:
-Addition and resolution of vector
1.計Net force
2.計Net moment
3.計relative motion(屬於力學,相對性原理,應該同newton's laws無關)
-Dot products
1.計Work done(屬於力學但應該同newton's laws無關)

認識vector對讀物理會有少少幫助,但即使唔識都好,都唔會有太大既影響。

都係物理的詞語,但向性同牛頓定律好似無關咁

唔會
vector & Newton's laws 無乜直接關係
