Another way to think about momentum is how hard it is to stop a moving object. It’s harder to stop an object moving quickly than an object moving slowly. What is the momentum equation? All moving objects have momentum. Momentum is a vector quantity which means it has size AND direction...

基本释义 [noun] the quantity of motion of a moving body, measured as a product of its mass and velocity [名词] 动量 深入解读 Momentum 是高中物理中出现的一个状态量,指的是“动量”,其量纲为物体的质量和速度的乘积,用来表示物体在其运动方向上保持运动的趋势。 从词...
This has something to do with the physics term—momentum, which is the quantity of movement of a moving object, measured as its mass(kg) multiplied by its velocity(m/s). Therefore, the unit of momentum is kg*m/s( or N*s). Also, momentum is a vector ( involving both magnitude and...

11. The changes of the electron transverse momentum are the basic factors of electron and photon scattering, and their differential scattering sections are decreased with increasing of the quantity of photons which are active with an electron at the same time, and they are quickly decreased with ...

Momentum is an important quantity because it is conserved. Yet it appears to not be conserved in the previous exampless, where large changes in momentum were produced by forces acting on the system of interest. Under what circumstances is momentum conserved? The answer to this question entails ...
