Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
speed does not include direction while velocity does.
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.
Velocity.

The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
speed does have direction :p
Speed in a given direction is velocity.
The amount of speed in a given direction is the 'component' of speed in that direction. The total amount of speed AND the direction of the total speed is the 'velocity' of the moving object.
Speed =distance/time Speed in a particular direction become velocity, a vector, which has magnitude and direction.
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
Speed in a given direction is velocity.
Speed and direction together are an object's velocity.
Velocity tells you the speed and the direction it's going. Speed only tells you the speed, with no direction.
Speed with direction is called Velocity
