- Now this energy spread is quite small, but then each atom will have some random velocity causing its energy levels to appear to shift due to the doppler effect.
- Outside the dead zone the higher random velocities can result in the destruction of smaller planetesimals, and the delay of the onset of runaway growth until planetesimals reach radii of 100 km.
- Since particle / antiparticle pairs emerge out of the vacuum-and since there is no " rest frame "-it seems like the particle pairs must be travelling at random velocities relative to my motion.
- In the case of turbulent flow, the fluid acquires random velocity components in all directions, including perpendicular to the length of the pipe, and thus turbulence contributes to the kinetic energy per unit volume but not to the average lengthwise velocity of the fluid.
- However, radiation that is streaming in a particular direction ( rather than suffusing an enclosed space ) cannot be said to be in thermal equilibrium with itself ( because it does not have appropriately random velocities ), so it does not have a true thermodynamic temperature.
- The problem here is that a single particle ( or even a collection of very few ) doesn't have a well-defined " average " velocity which we can identify to separate a bulk material velocity from a collection of random velocities ( whose corresponding kinetic energies count as heat ).
- There are two physical types of ellipticals; the " boxy " giant ellipticals, whose shapes result from random motion which is greater in some directions than in others ( anisotropic random motion ), and the " disky " normal and low luminosity ellipticals, which have nearly isotropic random velocities but are flattened due to rotation.
- The thing is, the molecules that collide more often will collide more often on the way out toward the wall anyway . . . the issue isn't how often they collide in mid-air, but simply how many, with a certain mass, and a certain range of speeds, are striking the outer edge of the container-which doesn't depend on whether they are big or small or how far they go before they bounce off the next molecule and draw another random velocity-- from the same histogram of speeds . talk ) 03 : 47, 4 July 2015 ( UTC)
