0 the force that keeps an object moving or keeps an event developing after it has started -- 动量，冲量；冲力；推动力；势头
In an attempt to give new momentum to their plans, the committee set a date for starting detailed discussions. 为了给他们的计划赋予新的动力，委员会确定了开始讨论细节的日期。
The play loses momentum (= becomes less interesting, energetic, etc.) by its half way stage. 这部戏演到一半时就没了看头。
The spacecraft will fly around the earth to gain/gather momentum for its trip to Jupiter. 航天器将绕着地球飞行以获取飞向木星所需的动力。
Once you push it, it keeps going under its own momentum. 一旦你推动了它，它就会在自己的动量作用下持续运动。
The laser eventually leaves the electron behind, with no increase in the particle momentum.
You kept up the momentum, and all your actors kept it up.
In classical mechanics, momentum is the product of the velocity and mass of a moving body.
For given layer densities and upstream fluid depths, the mass, momentum and energy conservation equations are obtained.
Whether the political will exists or can be generated to maintain this momentum, only the future will tell.
The pressure tensors in the momentum equations of ions and of electrons play two crucial roles in the collisionless magnetic reconnection.
The scalar potential in the continuity and momentum equations is taken as the linear combination of the electrostatic and self-gravitational potential.
Equations (12)-(15) represent the important conserved quantities of mass, momentum, the y component of the electric field and entropy.
