Speed is a measure of about how fast something moves. Velocity is the more accurate and exact description which must include both the speed and the direction of the object. Human walking speed is about 3 miles per hour. The car's speed was 60 km per hour.

A car driving north at 60 mph.
There could be another car, driving east at 60 mph.
The cars have equal speeds. But their velocities are different, because velocity is made up of
speed and direction.

constant velocity means the speed and direction are the same.
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
No, motion with constant velocity is not an example of motion with constant acceleration. Constant velocity means that the speed and direction of the object remains the same over time, while constant acceleration means that the speed of an object changes at a constant rate.
Of course. In fact, in order to have constant velocity, it must have constant speed.What you really want to know: Can a body have changing velocity when it has constant speed ?The answer to that one is also "yes", for example when it is moving in a circle, the speed is constant but the velocity is changing all the time (in direction).
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
An example of constant speed with changing velocity is a car moving in a circular path. The speed of the car remains constant, but the velocity changes because the direction of the car is constantly changing as it moves around the curve.
constant
Velocity magnitude is unchanging at constant speed. The direction might change (velocity is a vector with both size (speed) and direction) if , for example, you are driving around a curve at a constant speed.
rotational motion
You are driving your car with cruise control but you steer around a bend in the highway. The cruise control keeps your speed constant, but by steering you change your direction and thus your velocity is not constant.
Yes, a person running in a circular track at a constant speed of 7mph is an example of constant velocity and zero acceleration. While the person is changing direction, their speed remains constant, resulting in a steady velocity. Acceleration would only occur if there were a change in speed or direction.
Yes, an object can have a constant speed but varying velocity if it changes direction while moving at that speed. Velocity includes both speed and direction, so if an object is moving in a straight line at a constant speed but changing direction, then its velocity is constantly changing even though its speed remains the same.
