A change in the direction of motion IS a change of velocity,
even if the speed doesn't change.
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration".
Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
Well, Velocity is speed in a spefic direction so if it changes it direction it changes altogether. Sk8
Yes, acceleration is the how the velocity changes. This also includes when an object turns
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
"Acceleration" implies that the velocity changes.

The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
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.
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
