Brownian motion — the evidence

Brownian motion — the evidenceFree2:35Heddy Score 3 of 7, below the standard

What you need to know

  • Brownian motion is the irregular movement of small particles suspended in a fluid.
  • The movement results from uneven collisions with the fluid’s much smaller particles.
  • This visible motion provides evidence that the fluid’s particles are moving.
