Is it possible for the velocity to remain while the speed varies?
-and-
Is it also possible for the velocity to change while the speed remain as constant?
I need examples for m two questions...
... I know these might been so tough... but please help me find the answers...
Thanks!... To the one who will be a great help to me for this one, "I owe my homework to you"

Well, speed is what is called a scalar quantity, while velocity is called a vector. The difference is, a scalar has only size, while a vector has size and direction. This is a pretty huge distinction, since if you are in an airplane, knowing the speed alone is not enough to tell you where you are going to land. You must also know in what direction you are travelling. Based on these definitions, you can see that you can change velocity without changing speed by simply changing the direction in which you're travelling.

if im not wrong, hopefully tis helps...
velocity is somewhat similar to speed but most physicist use the term velocity as it's a more better word than speed...
velocity is constant thru out the distance until the end of the given distance...
vector is oso what physicist called a vector while speed is called a scalar quantity... a vector involves the direction, and the degrees... and to find a vector it involves tangent, cosine, sine so on and so for...

velocity - is a measurement of speed but in a particular direction
So it is possible for velocity to change while speed remains constant
It is not possible for speed to vary while velocity stays constant.

Velocity is speed and direction. Such as, 10 miles per hour going north.
You can change speed, while not changing direction.
You can change direction, while not changing speed.
But either way, you are changing velocity.

do you own a bicycle? Go for a ride,along a bicycle ;path,travel as long as you can within the hour,and return, you possibly will have arrived at your answers,have a good day

Speed is a scalar quantity. It has magnitude only.
Velocity is a vector quantity. It has both magnitude and direction.

As far as I know (for the past 60 years) they are identical, unless you new generation have changed physics.

Yes, it is possible. It is almost the same things.
