✔ 最佳答案
newton's first law 稱慣性定律
這定律說明物質的均速移動不須要有外力幫助
則是指沒有外力的時候，物質的移動速度永不改變。
例子:當你在太空的時候，你對一支筆施力，令它向前移動，只要你不暫停筆的移動，它向前移動的速度便好像不會減少一樣(太空不是絕對真空的，因此筆的移動速度也會受外力的影響)。

方向也不會改變

其實簡易一些來說則是指
F與a成正比

動者恆動
any boby will continue its state of rest or motion in a straight line
靜者恆靜
any boby will continue its state of rest or motion in a straight line (velocity = 0)
除非有外力破壞該恆久的情況
unless acted by an external force.

Newton's First Law states that any boby will continue its state of rest or motion in a straight line unless acted by an external force.
