Dear Aspirant,

Here is the difference between Speed and Velocity :-

SPEED :-

1. Speed is simply the rate of change of motion.
2. Speed is the distance travelled by a body in a  unit time.
3. Speed is a scalar quantity
4. Speed ascertains how fast a body moves.

Velocity :-

1. Velocity is direction-aware and it is the rate of change of position of an object.
2. Velocity is the displacement covered by a body in a unit time
3. Velocity is a vector quantity
4. Velocity ascertains the object’s speed and the direction it takes while moving.

Hope this helps.

Good Luck!
