Check what you remember
Read the wording for your board, then hide it and explain independence of components in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
Resolving horizontally gives zero acceleration so horizontal velocity remains constant, while resolving vertically gives a_y = −g.
