Friction must take kinetic energy out.(摩擦力一定抵消动能。)
Who thinks the kinetic energy has not changed?(谁认为动能保持不变？)
Kinetic energy before; kinetic energy afterwards.(之前的动能，之后的动能。)
Then it has kinetic energy.(之后它就有了动能。)
So there was a certain amount of kinetic energy.(因此，这里有一定量的动能。)
Well, kinetic energy has clearly increased.(动能定然增加了。)
That intelligent crafty and pure very like a whale expression of eyes mix-crystal kinetic body, let everybody circean.(看！那慧黠而纯真的眼神和晶莹灵动的身躯，真令人著迷。)
Kinetic energy is conserved.(动能是守恒的。)
The axes are comprised of a generalized homologous temperature, the normalized kinetic energy flux, and the net film thickness.(坐标轴包括广义同系温度，标量化动能以及净膜厚度。)
