Velocity tells you the speed and the direction it's going.
Speed only tells you the speed, with no direction.
In common language, the terms are used interchangeably. But in physics, speed is a scalar; velocity is a vector. That is, a speed is just a number (and a unit) - for example, 50 kilometers/hour. But when it is important to distinguish a direction, you talk about a velocity. For example, "50 kilometer/hour to the north". Velocity is a speed AND a direction. "50 km/hour north" and "50 km/hour east" are the same speed but different velocity.
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
velocity is speed with direction; velocity is a vector and speed is a scalar
Speed has no direction, velocity does.
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
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.

velocity is speed with direction; velocity is a vector and speed is a scalar
Speed in a given direction is velocity.
Speed has no direction, velocity does.
Velocity and speed are not synonyms.
SPEED has the speed only; while VELOCITY has the direction and the speed.
Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.
Speed in a given direction is called velocity.
Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed So a change in velocity means a change in speed.
Velocity is speed with a direction
