Description

Overview of the essential ideas for this option

B.3: Fluids cannot be modelled as point particles. Their distinguishable response to compression from solids creates a set of characteristics that require an in-depth study.

B:4: In the real world, damping occurs in oscillators and has implications that need to be considered.
