Exponential change
What Exponential change means in Physics A-Level, as defined for AQA.
Definition of Exponential change
Check what you remember
Read the wording for your board, then hide it and explain Exponential change in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The shape of the charging and discharging curves, which have a changing gradient rather than being straight lines.
