The one with greatest mass (the heaviest).
A "radar gun" is used by police to know the speed of fast moving vehicles. Velocity is a vector. That means it has magnitude and direction. Its magnitude is same as speed.
When the velocity of a moving object stays the same, it has a constant speed.
No, they are not the same! Velocity involves the speed and the direction of the moving object...
an acceleration of Zero, and a constant Inertia.
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.

same speed , coz velocity is constant velocity consists of speed and direction...
Same speed, same direction.
The word is "stationary" for not moving, and "constant velocity" for moving at a constant speed in the same direction.
direction
No. Same velocity means same speed and same direction.
constant
