带微积分的物理学
牛顿定律
描述了导致物体运动的原因。共有三个定律,可以简要地陈述如下:
第一定律:在惯性参考系中,除非受到合外力的作用,否则静止的物体将保持静止。
第二定律:在惯性参考系中,力等于质量乘以加速度(
F
→
=
m
a
→
{\displaystyle {\vec {F}}=m{\vec {a}}}
)
第三定律:对于每一个力,都有一个大小相等、方向相反的反作用力(
F
→
a
b
=
−
F
→
b
a
{\displaystyle {\vec {F}}_{\mathrm {a} b}=-{\vec {F}}_{\mathrm {b} a}}
)
每个定律将在每一节中进行更详细的讨论。
