Reference: AQA
A vector quantity, meaning it has both size and direction, so it can be positive or negative depending on the chosen positive direction.
A vector quantity, meaning it has both size and direction, so a change in direction at constant speed is also a change in velocity.
The vector rate of change of displacement, so it changes when direction changes even at constant speed.
A vector quantity, so it has both magnitude and direction, and is measured in metres per second, m/s.
Changes with the medium when a sound wave passes from one medium into another.
The speed of an object in a given direction, and a vector quantity.
