汉语拼音:dòng liàng
Kinetic energy can be destroyed, but momentum cannot be destroyed in the absence of a net external force on the system as a whole.
动能可以被毁,但是动量不能,在整个系统外力,不存在情况下。I'll give it a little bit more spin angular momentum, so now I move my left hand towards me and my. . .
我再给它多一点的角动量,现在我将我的左手朝我移动。However, momentum is always conserved in a collision, whether or not the collision is elastic.
然而,不管碰撞是不是弹性的,在碰撞过程中动量总是守恒的。If I put it on this side, torque is now in this direction, spin angular momentum is in this direction.
在这边,力现在就是这个,方向的,旋转角动量是,这个方向的。Angular momentum is conserved about this point Q, but only about that point Q.
角动量,在点Q守恒,也只有在点Q守恒。Virtual particles have energy and momentum such that the rest mass does not correspond to that of a real , free particle.
虚粒子具有能量和动量,以便其静质量与真实、自由粒子的静质量不同。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。Momentum, which is basically how much force it would take to stop a moving object.
动量,基本上就是要让移动物体停止运动需要使的力量。The spin angular momentum is now in this direction, so I'm going to give it a torque like so.
旋转的角动量现在是这个,方向的,我给它一个这样的力。
