(also equipartition of energy)
noun[mass noun] Physics
1The equal distribution of the kinetic energy of a system among its various degrees of freedom.
- The researchers expected the array to relax into a random equipartition of energies.
- In this work he gave what Thomson considered the first proof of the Waterston-Maxwell equipartition theorem.
- In the bacterium, equipartition might thus be achieved either if the cell divides at a length for which the homogeneous state is stable or if period-doubling occurs before or at an initial stage of cytokinesis.
1.1The principle that equipartition exists for a system in thermal equilibrium.
- The equipartition principle further predicts a measurable molar heat capacity for such an atom of 0.5R (about 1 cal /°C-mole) per degree of freedom.
- Relatively recent microrheology methods exploit the equipartition principle-where kBT drives each mode-through a generalization to viscoelastic materials including gels and cytoskeletal networks.
- According to the principle of equipartition of energy, the energy per degree of freedom for this kind of motion (called translational motion) is equal to 0.5RT, where R is the molar gas constant and T is the absolute temperature.
- Example sentences
- Eventually the flux goes to zero, in the equipartitioned regime, in which the signal consists of equal amounts of energy propagating in all directions.
- An equipartitioned beam in a radio-frequency linear accelerator is simulated.
