Momentum depends on the frame of reference, but in any inertial frame it is a conserved quantity, meaning that if a closed system is not affected by external forces, its total momentum does not change. Momentum is also conserved in special relativity (with a modified formula) and, in a modified form, in electrodynamics, quantum mechanics ...
The population momentum is calculated by dividing this final total population number by the starting population. [4] Momentum, Ω, can be expressed as: = In this equation, b is the crude birth rate while e o is the life expectancy at birth. Q is the total number of births per initial birth.
A form of Newton's second law, that force is the rate of change of momentum, also holds, as does the conservation of momentum. However, the definition of momentum is modified. Among the consequences of this is the fact that the more quickly a body moves, the harder it is to accelerate, and so, no matter how much force is applied, a body cannot ...

"Angel number 1234 indicates forward momentum and the present need of growth and progress in life. It is a definite sign of new beginnings and the need to focus on future goals."
The momentum effect raises a further important issue. If markets are rational, as the efficient-market hypothesis assumed, then they will allocate capital to its most productive uses. But the momentum effect suggests that an irrationality might be at work; investors could be buying shares (and commodities) just because they have risen in price.
The moment of force, or torque, is a first moment: =, or, more generally, .; Similarly, angular momentum is the 1st moment of momentum: =.Momentum itself is not a moment.; The electric dipole moment is also a 1st moment: = for two opposite point charges or () for a distributed charge with charge density ().
History shows us that even if Nvidia shares wallow in the doldrums for a time, this stock's long-term momentum is far from over -- and that's why it's still a top technology stock to buy and hold.
