No. Speed tells the size of velocity, but velocity
also includes the direction of the motion.

How can a vehicle at the same time have a constant speed but changing velocity?
Speed is a scalar quantity (direction does not matter) and velocity is a vector quantity) ie velocity means speed in a specific direction. If you are changing direction (turning) in a car, your speed is the same, while your velocity changes.
Is overall velocity the same as average speed?
No, velocity is a vector quantity (i.e. magnitude & direction) while speed is a scalar quantity (i.e. magnitude only).
Is speed a derived quantity?
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Does a speedmeter give instantaneous speed or velocity?
Velocity is a vector quantity, so a different direction makes a different velocity. Speed is a scalar quantity, where direction makes no difference. Since a speedometer reads the same regardless of direction of motion, it is providing speed, not velocity.
Can an object have a constant spped and velocity at the same time?
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
How do you compare velocity and speed?
Velocity is a vectorial quantity, speed with a direction.
Is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Could speed or velocity exist without time?
Speed is scalar quantity where as velocity is vector quantity. Unit is same as distance by time i.e. meter per second, kilometer per hour. Hence, either speed or velocity does not exist without time.
When an object's speed change does its velocity change?
Since speed is the magnitude component of the vector quantity of velocity, of course when speed changes velocity also changes. Speed is a one dimensional scalar quantity. Velocity is a three dimensional vector quantity describing both speed and direction of motion.
Is speed velocity in a given direction?
Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
What quantity gives both the speed and the direction of an object?
Velocity gives both speed and direction of an object. While speed is a scalar quantity, velocity is a vector quantity and require direction or bearing in order to be valid.
