Check what you remember
Read the wording for your board, then hide it and explain weight and upthrust in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
In a liquid, upthrust is not negligible, so the initial resultant force is weight minus upthrust, making initial acceleration less than g.
