Definition of momentum in English:

momentum

nounPlural momenta məˈmɛntəm

mass noun

1Physics
The quantity of motion of a moving body, measured as a product of its mass and velocity.
〔物理〕动量；冲量
Example sentencesExamples
- Most of the particles begin the procedure with positions and momenta that trap them within a well of potential energy; only a few have enough energy to escape over a barrier.
- By observing the particle types, numbers, and momenta in a jet, one can reconstruct the kinematic and quantum properties of the initially scattered parton.
- At any time, since the momenta of the two masses are opposite and equal in magnitude, the total momentum of the ‘device’ is zero.
- In contrast, the active medium in the mechanical laser is the intrinsic angular momenta of electrons and nuclei.
- As nuclei spin, the balance of factors is perturbed, and at very high angular momenta nuclei may adopt odd shapes resembling peanuts, bananas, jumping jacks, or sea urchins, among others.
2The impetus gained by a moving object.
冲力，势头
the vehicle gained momentum as the road dipped
下坡时，车辆冲力增大。
Example sentencesExamples
- The forest of streamers from the wharf to the ship's rail slowly broke as the vessel gained momentum.

- Its large pointed ears were laid back flat against its head as it gained momentum.
- He jumped off when the disk was close, using his earlier momentum to go speeding towards Valshar's body.
- Why is the law of momentum conservation not violated when a ball rolls down a hill and gains momentum?
- The strip strike set the hook, his speed and momentum carried the fish skywards, head shaking, gills flared.
- As the herd gained momentum the bells on the lead cows rang out louder and the erratic clanging became a regular tolling.
- Racing is all about momentum and carrying speed through corners.
- That tiny bit of motion gets a little momentum started that eventually builds to the bigger movement you're after.
- Scuba divers can glide peacefully once they build up some momentum with a few kicks.
- In order to fly, the Manx shearwater must be on a steep incline so as to gain momentum and height in the air.
