| 第一定律 |
除非受到外來的作用力，否則物體的速度(v)會保持不變。
|
Also known as law of inertia (慣性). |
第二定律 |
某質量為m的物體的動量(p = mv)變化率是正比於外加力
F 並且發生在力的方向上。 |
1) Also known as
law of acceleration.
2) Fnet = ma
3) Force has units of Newtons (N, where 1 N = 1 kgm/s2) |
第三定律 |
作用力(Action)與反作用力(reaction)是 (數值)相等且(方向)相反。 |
1) Also known as
law of action/reaction forces.
2) Forces that actually move an objectmust come from a different
object |
