How do two objects moving at the same speed 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.

∙ 13y agoA lot of people think that 'velocity' is just a fancy word for 'speed', that you use
when 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 cover
distance and what direction you do it in. If you're driving around a circular track at
30 miles per hour, your speed isn't changing; but your velocity is, because your
direction keeps changing.
Two objects moving at the same speed but in different directions have different velocities.
Because their directions are different.

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.
When does two objects traveling at the same speed have different velocities?
When they travel in different directions, obviously, since velocity is made up of a speed and a direction.
Two objects with the same velocity must be moving in the same?
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.
Can two object have the same speeds but different velocities?
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 can two different observers measure a different speed for the same object?
It depends on the observer's frame of reference. If both are stationary then an object's speed will be measured to be the same. If one or both are moving at unequal velocities, then the same object will appear to move at a different speed for each observer.

What two objects with the same velocity must be moving the same?
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.

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.
Can two object have the same speeds but different velocities?

Can two object's have same speed but different velocity?
=== === 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.
Why do waves change speed as they travel through earths layer?
Different materials have different velocities of sound propagation.
What is relative speed?
Relative speed is the speed between two moving objects with no regards to a fixed reference. Speed is how fast something is moving with respect to an object.
