Work as a Scalar Product

功作为标量积

You may enter values in any of the boxes below. Then click on the symbol for either the scalar product or the angle. The vectors F and d cannot be unambiguously calculated from the scalar product and the angle. If the angle is changed, then d will be placed along the x-axis and F in the xy plane.

您可以在下面的任何框中输入值。然后点击标量积或角度的符号。向量 F 和 d 无法从标量积和角度唯一确定。如果角度发生变化，那么 d 将沿 x 轴放置，而 F 在 xy 平面内。
