Two objects moving at the same velocity are moving at the same speed and in
the same direction. If you're sitting on either of them, the other one appears to
be motionless.

To objects with the same velocity must be moving in the same?
Same speed, same direction.
Two objects with the same velocity must be moving in the same what?
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.
Do two skaters traveling in different directions at the same speed have the same velocity?
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.
Is it possible for two moving objects to be at rest with respect to each other?
Yes. Consider both the objects to be moving with the same velocity in the same direction. Then, the velocity of one of the objects with respect to the other is zero and vice versa, i.e., relative velocity is zero. If the relative velocity is zero,i.e., one object appears to have zero velocity (no velocity) with respect to the other, then they are considered to be at rest with respect to each other.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
Is there more force created when 2 objects meet in motion or when 1 object is still?
Assuming all of the objects have the same mass, the answer depends on their combined velocities. If the combined vector component of velocity of two objects is the same as the velocity of the single moving object, then the force of impact will be the same. So if the two are moving in opposite directions along the same path, they will generate the same amount of force as a single object moving at a velocity that is equal to the combined velocities of the two. If the velocities are different, the force varies accordingly.
There is no unbalanced force actingf on a moving object how will the objects motion continue?
if there is a balanced force on a moving object (no unbalanced force) the object will continue moving with the same velocity
What will be the momentum of an object moving with a certain speed?
Momentum is mass times velocity. Note that velocity and speed are not exactly the same thing. Velocity is a term used in physics to define both the speed and the direction of a moving object, so if two objects are moving at the same speed but in opposite directions, they have opposite momentum.
If two objects have the same momentum do their velocities necessarily have the same directions?
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
What is the same as zero velocity?
Velocity is a relative term. If we call that the object is moving and in particular direction, then there must be another object present, from witch it is moving away. and we can not say, witch object is moving away. If all object maintain the same position in respect to each other then, we will call them to have zero velocity.
Compare how two objects moving at the same speed could have different velocities?
Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction. If two objects move in different directions, their velocities will be different, even if their speeds are the same.Velocity is a vector; to specify velocity, you indicate a speed (a magnitude), and a direction.

How is speed and velocity the same?
No, they are not the same! Velocity involves the speed and the direction of the moving object...
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Do two objects that have the same velocity always have the same momentum?
No, since momentum equals mass times velocity, if the masses of the two objects of equal velocity are different then their momentum will be different.
Why do objects remained at rest?
As you can observe, they will not ALWAYS be at rest. Objects have a tendency to remain at rest, because:* Inertia means that if no force acts on an object, it will remain at rest if it was at rest; or, if it was moving, it will continue moving at the same velocity. * Friction forces will usually slow objects down.
How can you calculate the velocity and acceleration of falling objects?
Acceleration:Always the same, doesn't need to be calculated. Acceleration of gravity = 9.8 meters (32.2 ft) per second2Acceleration of gravity is negative (points down).Velocity:(Initial velocity) + [ (acceleration) x (time) ]Positive velocity = moving upNegative velocity = moving down
Is a measure of an objects velocity the same as the measure of the objects inertia?
No.Consider a grain of rice and a banana. If you threw these at someone so that they were moving at the same speed, their velocities would be the same.However, you would hardly feel the impact of the grain of rice but the banana would hurt.The force of the impact is a measure of the relative inertia of the two objects.Where two objects are traveling at the samevelocity, the inertia is greater in that object that has the greatest mass.
If two objects have different speed can they have the same velocity?
No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.
Why all objects travel at the same velocity?
All objects do not travel at the same velocity. As an example, you should take a few minutes and think about an earthworm and a jet airliner.
What kind of speed does a moving object have when the velocity stays the same?
same speed , coz velocity is constant velocity consists of speed and direction...
