The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc

Speed :
1. It is the distance travelled by an object per unit time.
2. It is a scalar quantity.
3. Speed is always positive.
Velocity :
1. It is the displacement covered by a body per unit time.
2. It is a vector quantity.
3. Velocity can be positive, negative or zero depending on the displacement.
