(Each cell is also rotating, but these “internal” rotational energies are disproportionately small, and don’t add up to much, in accordance with the scaling argument that leads to equation 4.) Sometimes you can get away with using the average force and the average displacement, if you ...
Force, Momentum Change, and Motion 来自 AIP Publishing 喜欢 0 阅读量: 38 作者:Tiersten,S Martin 摘要: Classical equations of motion for open systems are discussed and the equation of motion for fixed volume systems is shown to be F = +Φ, where Φ is the momentum flux. Numerous examples...
How can a small force impart the same momentum to an object as a large force? How does velocity affect momentum? What is the formula for momentum? Momentum is a measure of How are velocity and momentum related? What is the equation for the law of conservation of momentum? How to find ...

百度试题 结果1 题目 In the momentum equation, for steady flow the net force on the fluid mass is equal to the net rate of outflow of momentum across the control surface. ()A.对B.错 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
This is the crucial contribution to ∇ * (ρv); the other two contributions vanish in this example. We have a net outflow of fluid, which causes a decrease in the density of the fluid in the control volume, in accordance with equation 5.John Denker...
(8.39)−∂p∂t=∂ρvx2∂x+∂ρvxvy∂y+∂ρvxvz∂z+∂ρvx∂t If desired, viscosity and other forces can be added to the pressure differential force on the left-hand side of the equation. Similar equations can be derived for the y and z directions. View chapter ...
