adj. circumferential
不要把沿圆周的切向加速度与向心加速度混淆。
Do not confuse ever the tangential acceleration, which is along the circumference, with centripetal acceleration.
上述函数决定离开圆周的偏移量和各线段的长度。
The functions above determine the offset from the circle edge and length of each line.
但是别把这个切向加速度,它是沿着圆周的,和向心加速度混淆。
Do not confuse ever the tangential acceleration, which is along the circumference, with a centripetal acceleration.
At any instant, your motion, if it follows any curve, locally can be approximated as being part of some circle.
在任何时候,如果做曲线运动,都可以近似地认为是圆周的一部分
I have shown you yesterday that the speed of the particle as it goes around the circle is this .
我昨天讲过,质点做圆周运动的速率等于这个
Different understandings of what that piece means gives you different values, and that's a bit of a problem.
应该是半径为1角度为,弧度为2比圆周率的一半,稍微多一点。
