Definition

The object's speed at the start of the time interval or measured section being considered, measured in m/s.

Used by OCR

Paper 1, Paper 2

Always calculate the change as final speed minus initial speed.
Revise: Acceleration and Equations of Motion

1
Write the change in speed as final speed minus initial speed: $v-u$ . Do not divide the final speed alone by time unless the object started from rest.
