Brownian Motion / Brownian Motion
What is Brownian Motion
The zig zag motion of a pollen grain in water or smoke particles in the air
Why Its moves this way?
Because the air particles bombards the smoke particles in all directions randomly at high speeds causing it go in zig zag motion.
(air particles is too tiny to be visible and smoke particles is much much bigger in size so air particles must be moving at high speed in order for the much bigger smoke particles to change direction
So its keep changing direction because air particles bombarding from all directions)
