Acceleration

Acceleration is the rate of change of velocity with respect to time, found by differentiating velocity: $a=\frac{dv}{dt}=\frac{d^{2}s}{dt^{2}}$. It shows how quickly the particle is speeding up or slowing down.

A negative acceleration while moving forward means the particle is decelerating.

You meet Acceleration in the Kinematics of Linear Motion chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Acceleration means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Acceleration (EN) · Pecutan (BM) · 加速度 (中文)
