In physics, however, they do not have the same meaning and they are distinct concepts. One major difference is that speed has no direction. Thus speed is a scalar. Just as we need to distinguish between instantaneous velocity and average velocity, we also need to distinguish between ...

Learn about the speed, velocity, and acceleration of an object in motion. Understand the relation between speed, velocity, and acceleration.
The velocity of an object is the speed of the object in a specified direction. Thus, if a plane is flying due south at 500 km/h, its speed is 500 km/h, but its velocity is 500 km/h due south. It follows that if the plane had flown in a circular path for one hour at a ...
