The position and momentum of the particle are observables.
Then the time average momentum of the particle is:
But let us determine the momentum of the particle by measuring the recoil of the wall.
The momentum of the particles is reduced as they ionize atomic electrons in the material.
"This has got to be a Heisenberg effect resulting from the zero momentum of the particles within the stasis field.
To demonstrate this mathematically, it suffices to show that the angular momentum of the particle is constant.
When traveling at higher speeds the momentum of the particles the ships will encounter will be large, and require more protection.
The force imparted by a gas particle into the container during this collision is the change in momentum of the particle.
In doing so, we find the momentum of the particle to arbitrary accuracy by conservation of momentum.
The net force on a particle is thus equal to rate of change of momentum of the particle with time.
And that the momentum of the particle p was related to its wavelength by what is now known as the de Broglie relation:
And of course, the momentum of the particle which is slowing down is NOT conserved.
This relationship indicates that the effective "deBroglie" wavelength is inversely proportional to the momentum of the particle.
Physically, U-processes occur when the final momentum of the particle points out of the first Brillouin zone.
Umklapp processes (or U-processes) change the momentum of the particle after scattering and are therefore limiting the conduction in semiconductor crystals.
Thus he stressed the probability of finding particles in the phase space, each state having volume h, and discarding the distinct position and momentum of the particles.
As the silicon detector is located within a magnetic field, the curvature of the path through the silicon allows physicists to calculate the momentum of the particle.
The COM frame can be used to find the momentum of the particles much easier than in a lab frame: the frame where the measurement or calculation is done.
When there is a loop, the momentum of the particles involved in the loop is not uniquely determined by the energies and momenta of incoming and outgoing particles.
When the target material is homogeneous and isotropic, the impact-parameter distribution is independent of the orientation of the momentum of the particle and interaction processes are also orientation-independent.
However later it was concluded that the paddle wheel turned not due to the momentum of the particles (or electrons) hitting the paddle wheel but due to the radiometric effect.
If the momentum of the particle is measured independently, one could compute the mass of the particle by its momentum and velocity (see Four-momentum), and hence identify the particle.
When the target material is monocrystalline, the yields of physical processes are very strongly dependent on the orientation of the momentum of the particle relative to the crystalline axes or planes.
When a constant force is applied to an object, it is the force multiplied by the time over which it is applied that yields the change of momentum of the particle.
It is a measure of the momentum of the particle, and it refers to the fact that a higher momentum particle will have a higher resistance to deflection by a magnetic field.
