1、

The next equation that I have is an obvious one, f= MA that is Newton's second law: f= MA.

那是很明显的等式,牛顿第二定律。

2、

F= ma mdv/ dt I can also write with this m dv/ dt.

所以,,F,=,ma,,so,therefore,也可以写成。

3、

OK, and so this is the notion of acceleration that's relevant to physics when you find F= ma; that's the that you have in mind here. It's a vector.

这就是加速度的概念,它和物理中F=ma的加速度是相关的;,这就是你们要牢记的,它是个矢量。

4、

Since F= ma, various body parts would accelerate slightly.

由于力等于质量乘以加速度,因而许多身体部位都会产生很小的加速度。

5、

F= ma I know, from Newton's Second Law F equals ma that there is no acceleration, so this must be zero so the sum of all forces on that mass must be zero.

根据牛顿第二定律-,合加速度为零,因此公式结果为零,整体中所有力的矢量和必为零。

6、

Remember when we had a spring, F= ma just a one-dimensional case, we had F equals ma,-kx and that, for the spring, became minus kx, and the minus sign indicates that it's a restoring force.

记得我们在上弹簧的时候,只是一维的情形,我们得到,对于弹簧来说,因为,减号意味着,这是恢复力。

互联网摘选

7、

The essential equation is simply F= ma, Newton's Second Law, where F is the sum of all the forces.

基本公式就是牛顿第二定律F=ma,F指各种力的总和。

互联网摘选

8、

This is the Second Law by Newton perhaps the most important law in all of physics F= ma but certainly in all of801: F equals ma.

这即为牛顿第二定律,物理学中十分重要的定律,本课程最重要的定律。
