Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.

What would happen to an objects's velocity if no work was being done on the object?
The velocity might still change, in the case of a force applied at a right angle to the movement. In this case, since the object's direction changes, its velocity changes.
Is a change in speed a change in velocity?
Yes. If the speed changes, so does the velocity.
Measures the changes in velocity?
A change in velocity is acceleration, so a accelerometer
Acceleration is the change of velocity?
Yes. To be more precise, the rate of change of velocity - how fast the velocity changes.
What tells how velocity changes?
The acceleration (the rate of change of velocity)

Is there any change in the vector if there is change in angle?
Yes. The angle is the direction of the vector, so if the angle changes, the direction changes.
What tells how velocity changes?
The acceleration (the rate of change of velocity)
What two things can change in velocity do?
motion and the angle
What changes in motion can result in a change in a change in velocity?
A change in velocity basically IS a change in motion.
What is the rate velocity changes?
The rate of change in velocity is known as acceleration.
Why is there a twist in a propeller blade?
to keep the angle under which propeller section sees the relative velocity. Because, a propeller essentially is a wing which rotates around an axis parallel to the flight velocity. wings operate best at a certain angle of attack, which is an angle at which wing 'sees' the flow. now, propellers rotate and tangential velocity increases from root to tip. airflow velocity is obviously constant. tangent of angle between relative velocity and prop section is air velocity / tangential velocity. we want angle between propeller section and relative velocity to constant, since tangent changes from root to tip , we need to change angle of propeller section itself.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
