Read the wording for your board, then hide it and explain Collisions and resultant forces in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Unequal collisions between the suspended particle and fast-moving fluid molecules produce a fluctuating resultant force on the particle.
