speed
•the distance travelled per second by moving object is called is speed.
•it is a scalar quantity . the speed doesn't not tell us directions of motion.
• the speed is always positive since direction is not taken into consideration.
•after one round in a circular path ,the average speed is not zero.
velocity
• the distance travelled per second by a moving object is a particular distance is called its velocity.
• it is a vector quantity. the velocity tells us the speed as well as direction of motion.
•the velocity can be positive or negative depending upon the direction of motion.
• after completing each round in the circular path, the average velocity is zero.

speed is a scalar quantity while velocity is a vector quantity speed depend upon distance travel and velocity depend on displacement
