Thermal velocity or thermal speed is a typical velocity of the thermal motion of particles that make up a gas, liquid, etc. Thus, indirectly, thermal velocity is a measure of temperature. Technically speaking, it is a measure of the width of the peak in the Maxwell–Boltzmann particle velocity distribution. Note that in the strictest sense thermal velocity is not a velocity, since velocity usually describes a vector rather than simply a scalar speed. Web{/eq} where {eq}v_{rms} {/eq} is the root mean squared speed of the gas molecules, R is the ideal gas constant, T is the temperature of the gas, and M is the molar mass of the gas. WebNov 6, 2024 · Consider a spring mass system as shown in the figure, excited by a harmonic force (sinusoidal). Then its response also will be in harmonic nature. Since Root Mean Square (RMS) Velocity represents the energy content of the signal, it is preferred over the peak velocity to measure the vibration amplitude. credit card group chat reddit
