It will typically look like this and the formula we say is F = - kx, where k is called "The force constant."
图像看上去一般就像这样,对应的式子是 F = - kx,k 叫做"弹性系数"
Then I know that kx is equal to the force that is exerting at this separation.
然后我就能知道 kx 等于,这个位置上讲台产生的力的大小
What's the difference between saying F = -kx and F = ma?
= -kx 与 F = ma 的区别在哪里
Maybe F = -kx should be called Newton's law?
也许应该把 F = -kx 称作牛顿定律
Other equation says F = -kx.
另一个方程是 F = -kx
