Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.
Velocity is a vector which incorporates both speed (a scalar) and direction. So the speed (distance divided by time) must increase if the velocity increases as the direction (an angular measurement) does not affect the absolute value of the vector.
Speed only tells how fast something is going, while velocity tells speed and direction.
Velocity
when you know both speed and direction of an objects motion you know the velocity of an object.
VELOCITY
By definition, it would have the same speed and direction as the compared object. This can be evidenced by the two objects having an unchanging spatial relationship: i.e. the objects remain the same direction and distance from each other.
angular velocity
accleration is the speed. Velocity is when you know the speed of an object and its direction.
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Speed and direction is called velocity.
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
