In bioinformatics, the root-mean-square deviation of atomic positions, or simply root-mean-square deviation (RMSD), is the measure of the average distance between the atoms (usually the backbone atoms) of superimposed proteins. Note that RMSD calculation can be applied to other, non-protein molecules, such as small organic molecules. [1]

If you feel the need, I do derive where it comes from, here. kB = 1.3806 ×10−23J/K is the Boltzmann constant. R is the universal gas constant, which in this scenario is 8.314472 J/mol⋅K.

WebRMS Velocity. The root-mean square (RMS) velocity is the value of the square root of the sum of the squares of the stacking velocity values divided by the number of values. The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path. RMS velocity is higher than the average velocity. WebJun 21, 2024 · Average kinetic energy = 3/2RT for 1 mole. For n moles, Average kinetic energy = 3/2nRT. Average kinetic energy = 3/2KT for 1 molecule. Here, K is called Boltzmann constant and this is equal to1.38 × 10 -23 J/K. PV = 1/3mn (v rms) 2. Here, m is the mass of one molecule. n is the number of moles. V rms is RMS velocity.

WebJan 20, 2024 · RMS velocity and average velocity are two different quantities that describe how fast something is moving in one dimension.You can calculate RMS velocity by taking the square root of the sum of the squares of the velocities along that one axis.
