Meaning
Brownian Motion is the seemingly random movement of very small, visible, particles when viewed under a microscope.
About Brownian Motion
- Brownian Motion is evidence of the particle model of matter.
- When viewed under a microscope small [[object]s like a pollen grain or tea leaf seem to change direction randomly.
- Brownian Motion can be explained if the small objects are being hit by other, even smaller objects that cannot be seen. This is evidence that matter is made of particles.
