这里有个法向力-,称之为。
所以在弧线上没有力,但是肯定存在法向力。
So there is no force along the arc, but there must be a normal force.
法向力不做功吗?
On this guy, I have 10 from the left 10 acting this way, 4 acting that way.
对这个物体,受到一个 10 牛的从左向右的力,10牛的力朝这边,4牛的力朝那边
Then, you may have forces to the right, forces to the left pushing, pulling.
然后你就有向右的力,和向左的力,推力和拉力都有
It says, if you pull it to the right, so that x is positive, the spring will exert a force which is in the negative direction; that's why you have a minus sign.
就是说,如果你向右拉,x 取正值,弹簧产生的力方向为负,这就是这里用负号的原因
