One example of Velocity is that if you are running in the same direction, your speed and velocity is the same. But if you are running AROUND the track, your speed is the same but your velocity is changing.
An example problem involving speed is calculating the average speed of a car that travels 100 miles in 2 hours. An example problem involving velocity is determining the velocity of a ball thrown upward with an initial velocity of 20 m/s at a height of 40 meters above the ground.
A non-example of velocity would be a stationary object at rest. Velocity specifically refers to the speed of an object in a specific direction, so an object that is not moving does not have velocity.
Acceleration
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.
Velocity is directional, so if something is accelerating in the opposite direction from the one it is moving it, there will come a point where it has 0 velocity but still has accelerating. If you throw a ball at the ground and it bounces, for example.
It is an example of a velocity.
The velocity of a cube is _?
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)

constant velocity means the speed and direction are the same.
Acceleration
Deceleration (or negative acceleration).

the velocity of an object is the size of the speed/magnitude plus the direction it is going in
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).
