Read the wording for your board, then hide it and explain Acceleration in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The vector rate of change of velocity, produced by a resultant force, and it can be positive or negative relative to a chosen direction.
In metres per second squared, it is in the same direction as the resultant force because the equation is vectorial.
