What is the difference between Brownian motion and Kinetic energy?

The definition for kinetic energy is atoms moving around (movement)

And the defininition for Brownian motions is also movement.



What's the difference?



Thanks!What is the difference between Brownian motion and Kinetic energy?No. The definition of kinetic energy is E=(1/2)mv^2.What is the difference between Brownian motion and Kinetic energy?
Kinetic energy is the energy associated with movement, this isnt necessarily just particles. It can be people, planets etc. Kinetic energy is a measure of how much energy the thing has in moving.



Brownian motion is the word used to describe the random movement of small particles moving under thermal motion. Each of these particles has kinetic energy, given to it by the thermal energy of the system, so they dart about randomly.What is the difference between Brownian motion and Kinetic energy?The real difference is that KE means energy derived from motion. Browning motion is motion or movement. And that's all it is; no energy connotation.



Brownian motion is usually attributed to the random movement of gas molecules as they are caused to move by heat energy. In turn, that random motion (random velocity) is manifest as a level of temperature, which is simply a measure of net average kinetic energy of the molecules.



So your definition "atoms moving around (movement)" is not the definition of KE. I don't know where you got that definition, but if I were you, I'd go back to my text and notes and revisit the definition of kinetic energy.What is the difference between Brownian motion and Kinetic energy?
Kinetic energy is 1/2 m v^2 (simply)

to be more precise, if you have a collection of things moving around - like in Brownian motion - the total K energy is KE= the sum of all individual KE's

and remember v is velocity which is a vector.

So if you have a lump of matter that is itself stationary (relative to your frame of reference ) the KE will be zero because all the random "brownian" KE's cancel out.What is the difference between Brownian motion and Kinetic energy?The term kinetic energy refers to all kinds of motions (earth, plane, nuclear radiation ...) and has an exact value. Brownian motion is a certain motion, observed in small particles and molecules. The particles may have kinetic energy due to Brownian motion.What is the difference between Brownian motion and Kinetic energy?
Kinetic Energy (in gases) is a result of Brownian motion of molecules.
