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.

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.

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.


Do things fall at the same speed?

In the absence of an atmosphere, all objects will fall with the same acceleration. If two objects of different mass begin with zero velocity and are released at the same time, they will fall at the same speed.


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.


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 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.



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.


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 terminal velocity the same speed for any weight?

Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.


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.


Is velocity for waves different than speed?

Speed and velocity are never the same thing.Velocity means 'speed' AND the direction it's going.


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 does two objects moving at the same velocity must have?

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.


Can objects have equal speeds without having equal velocity?

speed is a scalar and velocity a vector. Yes, they have equal speeds in the direction of the vector. If you run up a hill at 10 mph the speed and velocity in the direction up hill are the same, but the horizontal speed and vertical speed are different.


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.


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.


Is escape velocity same for all objects?

Yes. It is different for different planets etc. Escape velocity on earth is different than escape velocity on Jupiter.


How is speed of a body related its velocity?

Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.


Why the units of velocity and speed are same?

because they measure different aspects of the same thing, velocity also has direction but speed lacks direction. otherwise they are the same.


If two objects have the same velocity do they have the same momentum?

No, because momentum depends on velocity and mass so they may have the same velocity but if they have different masses then they will have different momenta. (momenta is the plural form of momentum.)


How speed affect the velocity?

Different words for same thing


Two bicycle riders have the same speed so do they have the same velocity please explain?

Not necessarily. Velocity is made up of speed and direction, so if they go in different directions, their velocity won't be the same.


Why is it that objects can accelerate at a constant speed but not at a constant velocity?

If the velocity is constant there is no acceleration. Speed is not velocity, velocity has speed and direction. I A car going around a circular track at 60 mph keeps the same speed but changes direction and thus accelerates at a constant speed. Velocity is speed in a certain direction. So change the speed but keep direction the same and you change the velocity. or Change the direction while keeping the speed the same and you change the velocity. If the speed is constant, any change of direction is a change in velocity. Driving around in a circle is a case of constantly changing direction.


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.
