Hi there,
I wonder if there is anything call mechanical motion(movement)? How does it compare to so called thermal motion? I know in microscopic area, particles are moving randomly due to thermal effect. If we call this thermal (Brownian) motion, so what's the name of motion of macroscopic object moving governed by Newton's law?
By the way, as we know, even we cool the object to 0K, there is still something called zero-point energy. So will particles move with zero-point energy? If so, how do we call this kind of motion (thermal motion is no longer suitable in this case, right?)
