What is the definition of velocity and how is it different from speed?

Velocity tells the speed and also the direction.
"30 miles per hour north" and "30 miles per hour west" are
the same speed but different velocities.

Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
What is the scientific definition of velocity?
Speed and acceleration.
How is velocity different that speed?
Velocity is a vector Speed is a scaler
What is velocity definition?
Velocity is the speed of an object.
Why speed is scalar while velocity is vector?
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.

Why there's a change velocity if you are changing direction?
Because that's the definition of 'velocity'.'Velocity' is not just a word you use instead of 'speed' when you want to sound smart.It's meaning is different from the meaning of 'speed'.'Velocity' has two parts to it . . . speed and direction. If either of those changes, thenthe velocity has changed.
What is the scientific definition of velocity?
Speed and acceleration.
How is velocity different that speed?
Velocity is a vector Speed is a scaler
Are speed and velocity different?
SPEED has the speed only; while VELOCITY has the direction and the speed.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
What is velocity definition?
Velocity is the speed of an object.
What is the definition velocity?
Speed plus the direction of travel.
Why speed is scalar while velocity is vector?
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
Can an object acceleration if its velocity is constant?
No. It is a matter of definition. Acceleration is defined as a change of velocity. Technically, one must distinguish between velocity and speed. Velocity is a vector and includes the information about the magnitude (speed)and direction. One can have a constant speed and an acceleration (as in circular motion) but, by definition, constant velocity means zero acceleration.
What is group velocity?
The official definition for the word group velocity is "the speed at which the energy of a wave travels."
