Acceleration (Grade 10 NSC Matric Physical Sciences): Flashcards

How quickly an object's velocity changes over time

$a = \frac{\Delta v}{\Delta t}$

$m \cdot s^{-2}$ (metres per second squared)

Vector quantity (has magnitude and direction)

Object speeds up

Object slows down

Change in velocity (in $m \cdot s^{-1}$)

Change in time (in $s$)

Choose a reference frame (decide which direction is positive)

Average acceleration equals instantaneous acceleration
