1.动能
1.the energy that an object has as a result of moving
1.Maybe the sun is spinning down, is slowing down and maybe the energy that we get is nothing but rotational kinetic energy.
也许太阳转速正减慢，也许我们得到的能量，不是别的，而是旋转动能。
2.Now the energy that we're trying to capture is kinetic energy of these fission products.
现在，我们能够尝试获得的能量，就是这些裂变产物的动能。
3.So now here you see in front of your eyes a case that the wall has momentum, but it has no kinetic energy.
你在这里看到，亲眼看到这个例子，墙壁是有动量的，但它却没有动能。
4.When a torque is applied to a body, potential energy is imparted to the body, which accepts it in the form of kinetic energy.
当物体上作用一力矩时，把位能给予了这个物体，物体以动能的形式接受这位能。
5.A proportion of that energy is now stored in the vehicle and is called kinetic energy.
汽车从原地起步加速到某一速度需要能量。储存在汽车中的那部分能量称为动能。
6.And I want to know at this moment how much kinetic energy of rotation is stored in that disk.
我想知道现在，这个磁盘内蕴含，多少旋转的动能。
7.Whether the door to consider the pace of movement, or kinetic energy of the size of the door movement, must ensure the safety of passengers.
无论考虑门运动速度的快慢，还是门运动动能大小，都必须确保乘客的安全。
8.The energy required to lift something away from the Earth is equal to its kinetic energy if it were moving at Earth's escape velocity.
将物体送离地球所需要的能量等于逃离地球的宇宙速度所需的能量。
9.The energy possessed by an object by virtue of its motion is called kinetic energy, or energy of motion.
物体由于运动而具有的能量叫动能。
10.Just to be clear, the jumper velocity (and thus kinetic energy) of the jumper at the top and the bottom are both zero.
我来解释一下，整个跳楼过程中，跳楼者的速度（由此便产生了动能）在起跳处和着地处都为零。
