Speed units examples
WebSpeed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. WebThe angular speed of Earth is 1.99 x 10 -7 radians /seconds.
