Question

Why do we use RMS speed?

Answer 1

Explanation:

The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas. ... The root-mean-square speed takes into account both molecular weight and temperature, two factors that directly affect the kinetic energy of a material.
