First of all ... I think you're talking about either the magnitude of the momentum, or the magnitude
of the velocity, not the magnitude of the objects.
Now ... you're obviously skating around the subject of vectors here, recognizing that both the
velocity and the momentum are vector quantities.
If, as you say, the two objects have " ... the same momentum ... ", then you're saying that their
momentum vectors are equal. If so, then you'd have to say that yes, since the momentum vectors
are equal, the momentum vectors and the velocity vectors must all have the same direction.
But if the two momenta only have equal magnitudes, then they ... and the velocities ... can be in
any two directions, not necessarily related.
You take square roots out of numbers, and certain physical magnitudes (measurements and the like), not out of objects.
The more inclined the plane, the more momentum an object will gain while going down it.
100%. UFOs can be any unidentified flying objects. They don't necessarily have to be driven by aliens.
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.

Yes. If the force of momentum is equal in both directions, the momentum will cancel. This can occur if two objects with equal momentum traveling in different directions collide.
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.

It is due to the momentum of the two bodies.
a moving objects momentum
Rotating objects all have angular momentum.
Momentum
Yes: P=mv (momentum = mass * velocity)
One object that has a momentum is a computer.
conservation of momentum
momentum (vector)
The momentum can be cancelled when the objects are equal and opposite in momentum, 0= p1 + p2, thus p1=- p2. Newton's 3rd law.
