The coefficient of drag and coefficient of lift in the circumstance of rotating wheels is lower.

汽车在车轮旋转情况下，阻力系数和升力系数比车轮静止情况下的低。

It appears, however, that the "drag coefficient", CD, also depends on the velocity of the ball.

然而，阻力系数CD，也取决于球的速度。

Assuming that the amount of spin had not decayed too much, then the drag coefficient increased.

假设转速衰减很少，那么阻力系数增加。

The coefficient of drag for 2013 has been improved to 0.28 (versus the previous 0.29).

Surely the most underappreciated number in the Ram spec sheet is its 0.36 coefficient of drag, given that the 2013 Ram's grille is larger, higher and more bluff than before, recalling the big-rig aesthetics of the mid-1990s.
