Speed is a scalar magnitude (it only tells you how much). Velocity is composed of the object's speed and the direction in which it's moving. This corresponds to the definition of a vector.
Using "miles" and "hours" as an example:
Therefore, when a vehicle travels on a winding road maintaining a speed of 30 mph, its speed remains the same but its velocity is changing with each turn.
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
angular velocity
...travel in different directions relative to a reference point. Velocity is a vector quantity that includes both speed and direction, so even if objects are moving at the same speed, their velocities can differ if they are moving in different directions.
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.
Centripetal forces can.
That is called "velocity".
Terminal velocity if it has reached its top speed. Or obviously constant speed.
