The rate of change of displacement, including the direction of motion; it is a vector quantity.
Revise: Scalar and vector quantitiesSpeed and velocity are similarly related. Speed tells you how fast an object moves. Velocity tells you how fast it moves in a particular direction.
- Revise: Velocity
An object's speed in a given direction.
- Revise: Calculating Acceleration and Uniform Motion
Speed in a stated direction; it is a vector quantity measured in metres per second, m/s.

- Revise: Newton's First Law
Speed in a given direction.
- Revise: Momentum is a property of moving objects
Speed in a particular direction, measured in metres per second (m/s).
- Revise: Changes in momentum
Speed in a stated direction, measured in metres per second (m/s).
- Revise: Orbital motion, natural and artificial satellites
Speed in a stated direction. Changing direction changes velocity even if speed stays the same.
