Speed:
1.Rate of change of distance with time.
2.Scalar quantity
3.It indicates rapidity of object
4.When the body returns to its initial position, speed will not be zero
5.Speed can never be negative
Velocity:
1.Rate of change of displacement of a body with time
2.Vector quantity
3.Along with rapidity, it indicates direction of a object
4.When the body returns to its initial position, velocity can be zero
5.Speed can never be negative It can either be negative or positive, sometimes zero
