When they travel in different directions, obviously, since velocity is made up of a speed and a direction.

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.

Can two objects have a different speed but the same velocity?
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.
How could two observers measure a different speed for the same moving objects?
They would have to have different base velocities. One on the ground, the other in a moving vehicle.
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.
Can two cars of equal speed have equal velocities?
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
How do two objects moving at the same speed have different velocities?
A lot of people think that 'velocity' is just a fancy word for 'speed', that you usewhen you want to sound smart. But it isn't. The two words mean different things.'Speed' just means how fast you cover distance. 'Velocity' means how fast you coverdistance and what direction you do it in. If you're driving around a circular track at30 miles per hour, your speed isn't changing; but your velocity is, because yourdirection keeps changing.Two objects moving at the same speed but in different directions have different velocities.Because their directions are different.
How could two objects travailing at the same speed have different amounts of momentum?
Momentum is both speed and mass. So if two objects are traveling at the same speed then the one with more mass will have more momentum.
What does Newton's Law of gravity say about two objects?
They fall at the same speed even if the mass is different that is upon a vaccum mass wont matter velocities would be equal as gravity acts uniform to al objects.
What is used to describe the behavior of extremely small particles traveling at velocities near the speed of light?
Quantum Electrodynamics theory
What is the speed of most objects and what it depend on?
Different objects can have different speeds; also, the same object can have one speed now, and a different speed later.
If a car is traveling north at 100 kilometers per hour and another car is traveling in the opposite direction at the same speed Are their velocities the same?
No. Velocity includes a directional component. If the two were of the same mass and collided head-on, their velocities (being in the reverse directions) would cancel out.
Which System of mathematical equations is used to describe behavior of small particles traveling at velocities near speed of light?
Schrödinger's equations, I believe
Why do waves change speed as they travel through earths layers?
Different materials have different velocities of sound propagation.
Does motin occurs when there is a change in speed?
ans: do you mean motion? motion is the meaning to move relative to something else, and it occurs (or is seen to be occurring) when two objects pass each other that have different velocities (not necessarily changing velocities). Without this, you would not be able to perceive motion at all. Motion doesn't mean speed has to change, as that relates simply to acceleration.
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.
Which is an example of velocity?
Take a train going west at 100 miles per hour and another train going south at the same speed. Their velocities are different because velocity is a vector quantity that gives both speed and direction. Since they are going in different directions they have different velocities.
What does a diagram of two objects with the same speed but a different velocities look like?
The diagram you are asking for looks like two lines, with the same length, but pointing in two different directions. The difference in direction is what would show the different velocity. So imagine one line going down, one like going right, same length, but directions, so they would be different velocities.
Do Two cars traveling the same speed in opposite directions have the same velocity?
No, because velocity includes direction as well as speed.In order for the velocities to be the same, they would have to go the same speed in the 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.
Is 2 vehicles having different speed but same distance have same velocities?
No. Same velocity means same speed and same direction.
What is the definition of velocity and how is it different from speed?
Velocity tells the speed and also the direction. "30 miles per hour north" and "30 miles per hour west" are the same speed but different velocities.
Do objects travling the same speed have the same velocity?
Not necessarily. "To have the same velocity" means to have the same speed AND move in the same direction. A car driving north at 30 miles per hour and another one driving south at 30 miles per hour have the same speed but different velocities.
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.
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.
