Momentum is the physical movement of mass m with speed v or velocity V creates momentum p =mv or p=mV.
Every spec of moving mass creates momentum. This makes momentum a very big deal in physics. Momentum also creates scalar and vector energy cp and cP.
Vector Momentum Energy cP is the mysterious "Dark Energy". it is mysterious because physicists define energy as a scalar and thus overlook, vector energy.
The famous Tangent Vector Force F=mdV/dt is the Momentum Force dcP/dr = dcP/cdt = dP/dt = dmV/dt = mdV/dt.

What is physical significance of momentum?
Physically, linear momentum is "stored force" as that momentum is dissipated. Consider the linear momentum of a train carrying coal coming to a stop, quickly.
What is physical meaning of momentum thickness?
Physically the momentum thickness may be conceived as transverse distance by which the boundary should be displaced to compensate for the reduction in momentum of the flowing fluid on account of boundary layer formation.
What is momentum apart from physical quantity?
an unchanging state
What is angular mementum?
Angular momentum is the moment of momentum, a conserved vector quantity used to state the overall condition of a physical system.
What is physical significance of linear momentum?
The same as momentum - sometimes called "linear momentum" to distinguish it from angular momentum. Linear momentum is the product of mass times velocity. It is a conserved quantity, making it very useful for certain calculations.
How do you find the momentum with no velocity?
It is unclear what you mean. If you mean that you want to find momentum but do not have a value for velocity then it depends on what physical system you are using. If you want to find the momentum of an object with a velocity equal to zero then the momentum is zero. Answer2. You can find the momentum from its the integral of its force impulse fdt = d(mv). The momentum is mv= integral of fdt.
How do solve conservation of angular momentum?
Usually you would use some fact you know about the physical system, and then write an equation that states that the total angular momentum "before" = the total angular momentum "after" some event.
Why do you think you cannot Chang a element by a physical or chemical change?
The change in momentum depends on the
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
Meaning of a physical needs?
1. meaning of physical needs?
What is the momentum in kg-m?
Momentum is actually measured in kilograms x meters/second, since it is the product of a mass and a speed. Momentum can be thought of as the "amount of motion", and it is a physical quantity that is conserved under all circumstances, as far as we know.
Does momentum mean speed?
Not exactly - momentum is more the build up of speed instead of speed itself. Speed is a measure of how fast you are moving, whereas momentum is how mcuh speed you're using.. If that makes sense. As defined by dictionary.com, momentum is force or speed of movement; impetus, as of a physical object or course of events.
