WebAboutTranscript. Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the ... WebSpeed is a scalar quantity while velocity is a vector quantity. This means velocity indicates speed with a direction. If a body is moving with constant velocity, it means the body is moving with a constant speed in a particular direction. Is a vector speed or velocity?
