The velocity of an object has two attributes, 1. its magnitude and 2. its direction. The difference betwen the velocity and the magnitude of the velocity is the direction!
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
Answer: No, the speed is constant, but the velocity changes, since the direction changes. Please be sure you understand the difference between "speed" and "velocity", as used in physics. Speed is scalar which has only magnitude but not direction Whereas velocity is having both. So is a vector quantitiy
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
If the velocity is zero, the object is not moving. So if it moves at all, it is changing direction.
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.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction).
First, note that velocity is a vector quantity. This means it has a magnitude (the speed) as well as a direction. The magnitude of the velocity is the difference in position divided by difference in time. Hopefully, the direction should be evident from the graph.
The magnitude and direction of the object's velocity vector.
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.

That's the magnitude of its acceleration.
"Acceleration" implies that the velocity changes.
Velocity is the rate of change of distance with time, acceleration is the rate of change of velocity with time.
If the velocity is zero, the object is not moving. So if it moves at all, it is changing direction.
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
