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 - Speed is the Measuring the rate of motion.
1. Speed is a scalar quantity, that means it doesn't specify the information about the direction.
2. Speed of an object tells us how fast does it move.
3. The average speed of a moving object is always finite and cannot be zero.
4. It is the distance covered per unit time.
5. Speed of an object is always positive.
VELOCITY - It is speed with direction.
1. Velocity is the vector quantity, it means that it provides information about the direction as well.
2. Velocity of an object tells how fast and in which direction the given object moves.
3. The average velocity of a moving object can be zero too.
4. It is the displacement (i.e., distance covered in a particular direction) covered per unit time.
5. Velocity can be positive or negative.
