If my force of pushing is less than the force of friction, then the TV set will to decelerate.

如果推力小於摩擦力, 则电视会慢下来。

It will take seven minutes for Phoenix to decelerate from nearly 13,000 miles an hour to a soft touchdown on Mars.

The slower pace allowed the cats to quickly decelerate and reaccelerate into fast, tight turns — the better to avoid getting faked out by prey.

较慢的速度让它们能立刻减速和再加速来急转弯，因此它们更不容易被猎物的假动作欺骗。

So we don't have all the details yet, but from what we've seen in past Mars missions, the lander will need to decelerate from its release in the Martian atmosphere to a safe landing on the surface.

所以我们还不知道所有的细节，但从过去的火星任务来看，着陆器在进入火星大气层后需要减速才能在火星表面安全着陆。
