The relationship between speed and velocity is magnitude, it is the connection between speed and velocity.
Explanation:
Speed measures the fast movement of a person, it does not bother about which direction, whereas velocity looks over the direction. Speed understands fast movement, velocity understands directions.
The relationship between speed and velocity is magnitude, it is the connection between speed and velocity. The speed is the magnitude of the velocity.
Speed is scalar quantity and velocity is victor quantity. Scalar quantity is measure by units of distance by time and vector quantity finds the magnitude and time of a travel.
