Reference: AQA
A quantity that includes both speed and direction, so a negative value means motion opposite to the chosen positive direction.
Velocity includes direction, so a change in direction is a change in velocity even if speed is constant.
Speed in a stated direction, so a change in either speed or direction is a change in velocity.
