Their 'sizes' are. But if you want it to be a velocity, then
you also have to tell the direction of the speed.
They have exactly the same size. The difference is that 'velocity' tells you which way the 'speed' is going.
No. Speed is the magnitude of the velocity vector. If velocities are the same, their magnitudes are the same, which is another way of saying that the speeds are the same.It can work the other way around, however ... same speed but different velocities, meaning same speed in different directions.

Essentially velocity is speed and you mesure it in the same way as you would speed, MPH (miles per hour). Hope that does it for you, Thomas White
The size of the velocity is the speed, and you calculate it the same way. But whenyou find the size of the velocity, you're not done yet, because you also need itsdirection.
Speed is measured by dividing your time into distance to come up with your velocity. speed is measured the same way as velocity. If you have a varying speed with acceleration and deceleration this would need to be factored in as well.
Why? Because that's the way speed and velocity are defined.
Not exactly. Let me explain:Speed is one part of velocity. If you're measuring velocity, you have to know thespeed. But that's not all. For velocity, you also have to know the direction.
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.

No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.
