Speed is just the magnitude: "That ship is traveling at 20 knots." Velocity is a "vector" quantity, so it includes not only speed but also direction: "That ship is traveling NNW at 20 knots."

Speed - scalar quantity; velocity - vector quantity

Speed, being a scalar quantity, is the rate at which an object covers distance. On the other hand, velocity is a vector quantity; it is direction-aware.

Speed is a Scalar unit speed can be described as magnitude S=D/T (Distance traveled by time taken to travel that distance) Please note in the above equation there is no direction mentioned. Eg. A car is travelling at 10 meters per second . In this example we understand that the car is going...

Speed is a Scalar unit speed can be described as magnitude S=D/T (Distance traveled by time taken to travel that distance) Please note in the above equation there is no direction mentioned. Eg. A car is travelling at 10 meters per second . In this example we understand that the car is going at a speed of 10 meters per second. Velocity - Velocity is a physical quantity, both magnitude and direction are required to describe it. Eg. A car is travelling at 10 meters per second heading north. In this example we can understand that the car is travelling at a speed of 10 meters per second and heading in the Northern Direction. This direction makes velocity a vector unit. In a nut shell: Speed has no direction, Velocity does. read less

Will make you love maths

Speed has no direction and so it is a scalar quantity but velocity has a fixed direction and so it is a vector quantity.

There are scalar and vector quantities. Scalar quantities are only magnitudes whereas vector quantities are the quantities which have magnitude along with direction. Speed is distance/time. Whereas velocity is displacement/time.. In simple words, if we give direction to the speed, it is velocity. e.g....

Whereas velocity is displacement/time.. In simple words, if we give direction to the speed, it is velocity. e.g. speed of a train is 50km/hr. If train is moving in north direction, then velocity will be 50km/hr in north direction. read less

Speed is a scalar quantity whereas velocity is a vector quantity. speed does not require direction to describe it fully whereas velocity requires direction to describe it completely.
