Acceleration
OCRGCSE
Acceleration is a fundamental vector quantity in OCR GCSE Physics, defined as the rate of change of velocity and measured in metres per second squared (m/s²). Mastery of this topic requires confident use of two key equations — a = (v−u)/t and v² = u² + 2as — alongside the ability to extract acceleration from the gradient of a velocity-time graph. This topic carries significant exam weight within Topic P2 (Forces) and underpins Newton's Second Law, projectile motion, and terminal velocity, making it one of the highest-leverage topics a candidate can revise.
