Velocity and Speed are terms used in physics. Both are used to calculate the distance between two points. It is effortless to think both velocity and Speed are the same; in fact, many people use the words interchangeably. But the truth is, velocity is quite different from Speed. Velocity can be defined as the rate of change of displacement concerning time. It is used to determine the distance of an object from one point to another concerning time in a specific direction.

And that is why velocity is a vector quantity because it has both magnitude and direction. The SI unit for velocity is meter per second. Speed, on the other hand, can be defined as the total distance covered by an object concerning time. It is a scalar quantity because it has only magnitude but no direction. The SI unit for Speed is a meter
